Wow. I took a gamble picking a couple of these up. 
mainly I was playing a tournament and a guy was putting with one. I had heard about it. Asked to check it out. It felt great. A lot like a Luna or roach. And I like those beadless smooth rounded feeling putters. 
 

I would say the flight was not very overstable. 
it was more 2/3/0/1 for me maybe a 2.5 in speed. 
but not fast or slow. Just. Average. Not too glidey or a brick. Just. Enough. You don't want to sail past the basket. 
Muse to me is like a Luna after Thanksgiving. 
it just feels like a fatter Luna. Not by much. 
a tick slower and tick less glide than a Luna. Similar stability. Really like it. Honestly it's my favorite feeling putter ever. I had a recent hand surgery that's really messed up my life haha. Sucks. The only putter that actually feels good to grip still is the Muse and the RDG Serpent because they are a little chunky. 
 

the plastic is decent. A lot like a MVP electron medium. Not my favorite but it's decent. Medium flex. I still think trilogy medium blend is the best thing ever. Dang give me a Muse in a gray medium burst blend and I'd be happy 

My Nerve Muse looks great and throws great.  I recently got it as have been loving TSA plastic and wanted to try a putter.  I putted well with this.  The biggest complaint was in the Nerve plastic durability.   The Nerve plastic felt great, but the basket took a chunk out of disc on the first putt and could see piece of the plactic on the metal of band and never had seen a putter do that ( I did hit band so..). 

Love the nerve muse for putting. Just want to throw out that I ordered 2 bodanza muses and they are also uv reactive. Kinda threw me off when I first played with them. 

Got these to start trying new putters out. They felt great in hand before i even got a putt with them in. They come out of the hand so smooth even when im missing. Great depth for someone with slightly smaller hands. Nerve plastic is gummy but still stiff kind of like a R-blend. Can't go wrong with these if you want to give them a try! TSA Has some great quailty disc in my opinion!

This has been my go to putter. Fits my hand and the flight is consistent with a predictable fade that helps drain putts.

Have been throwing the first run nerve muse (bunny stamp).

Similar wing shape to a Luna or a Roach but slightly deeper and more torque-resistant. Like most other moderately overstable putters, likes to be thrown with a little bit of hyzer for a nice predictable flight and left-fading finish. Have not thrown the second run softer nerve but they looked more puddle topped, which should be a nice lower-glide option. I Am holding out for a premium plastic Muse TSA!

The Muse was my least favorite disc I used from the thought space lineup. I mostly tried it for putting and maybe as a thrower this disc will work great. But for me the muse was bulky and just did not fit my putting style in anyway. I recently switched my putting style to a more spin putt and I like to rest my index finger on the outside of the rim. With the muse being such a rounded disc I was not able to find a comfortable feel. I have seen multiple people putt extremely well with the muse and I know it was more of a personal problem with not liking it. If you are someone who loves beadless putters I think you would love the muse as your putting putter and you will not look back.

I got one of these from a friend at a tournament this putter is a phenomenal driving putter. If you like driving putters like myself this is a must-get. It is a great, stable torque resistant disc. As for stability, I don't think this is overstable but more akin to the stability of a Luna where it will hold a line and won't stray from it. 

The baseline plastic is a bit more slick than other brands, but it seems high quality and beefy.  Great stamp (as usual with TSA), and I like the flight of the disc.  It is very torque resistant, and could be a great driving putter.  Probably a bit to overstable for putting.  I just don't love the feel of the disc.  It is deep with a beefy blunt nose.  Not comfortable for me, but likely feels great for others. I greatly prefer the feel of the Praxis.

The plastic feels great and I really like the artwork TSA is putting on their discs. It's a bit of a deeper rim / beefier feel in the hand than I prefer for my putters. Not sure if it will make my bag for that reason but it's worth trying if you like more that style of putter.

I have been really enjoying Thought Space's plastic, and I am always on the quest to find that perfect putter that I can connect with so I decided to give the Muse a try.  My first impressions I wasn't thrilled with it.  I really like the plastic, but the feel in the hand was a little odd for me.  I decided to still give it a try since I had bought it, and it immediately became my go to putting putter.  I'm not sure if it is the plastic or the hand feel (thought I initially thought was odd) but I get a cleaner release out of this disc than any other putter I have tried.  I wish it wasn't quite as overstable.  It has a tendency to dump out to the left from 25 and out, but the low glide keeps the disc close making come backers a breeze.

These are my new putting putters. The plastic is firm and grippy which is excellent for me as a spin putter. The Muse is flat with a round beadless edge which allows for a very clean smooth release. The putter is in the middle as far as depth goes. I have larger hands and it feels very comfortable. It may be just a hair deeper than an aviar.

As far as driving with this putter I don't think I would want to until they bring it out in a more durable plastic. My few putting practice rounds show on the rim and I think one tree hit would pretty much be the end for these.

The Muse is my new putting and overstable approach putter. I absolutely love the feel of rounded rim and the Nerve plastic has a nice hard, tacky feel to it. I don't drive with it so I cant say how it flies off the tee, but for my shorter upshots it has a nice straight flight with a predictable fade. when putting, it flies laser straight when spin putting

Mine wants to fade out on an anhyzer fairly easily, so I compliment this disc with a keystone for a more understable putter with a similar feel in the hand. 

Really enjoy using the Muse for anything in circle 1 as this has become my main putting putter. Has consistent low speed fade at the end of flight making it predictable. The Nerve plastic is great for a base plastic and it seems to grip the chains pretty well. Have not used this as a throwing putter yet as I'm not sure how the plastic would take to a tree when my aim is off. Overall, this is a great disc and is worth trying out if you are on your own putter hunt. Give it a try. 

So far I have nothing but good things to say about the Muse. Feels great in hand, feels great on release, feels great to have a putter I am super excited about. Plastic is nice and grippy and seems to be a pretty solid in-between of premium and base plastics. 

I haven't thrown this putter as an approach or off the tee yet since I've got several other putt and approach discs to cover those shots but my putting with it has been consistent enough that I am pretty sure this is going to become my main putting putter. Fantastic disc and really cool stamp, cant beat it. 

The Muse is a pretty good putter. The plastic has an interesting feel to it. It is pretty stiff, and offers a lot of grip to it. Making the plastic pretty good for a base plastic. It seems to grab the chains really nicely when putting. The rim is pretty rounded, it feels kinda like a Luna,shape-wise that is. It fits pretty comfortable in my hand, when fan or power grip. And the grip is pretty solid, it inspires confidence.

I found this to be pretty neutral of a disc, which makes it be a great putter to be in a base plastic. It can do a lot of different lines. It is quite the versatile disc. It beats in pretty nicely, to provide a dependable flight.

Overall, I really enjoyed throwing this disc around.

The Muse is the second putter from TSA, but it's the first one to be produced in baseline "putting" plastic. It's NOT manufactured at the MVP facility as with all other current TSA molds. 
 

It's pretty much a Luna as far as feel and flight. Plastic texture is the biggest difference.  I'm tired of paying PMcB taxes to play with Lunas and I love TSA so it was an easy switch, haven't looked back. i can't wait until this gets produced in a premium plastic because it flies wonderfully off the tee but one terrible tree later will destroy baseline plastic. 

Feels A lot like the Luna in the hand. Brand new baseline plastic unlike anything I've felt before but it's great! Almost like a baseline neutron blend. Very grippy and great release out of the hand with a rounded edge and no bead. Definitely give TSAs newest putter a try if searching for a putting putter or something for approaches!
