A really great under the radar disc that does a lot of things well! When used for putting it flies a lot like an aviar. For throwing it flies very straight start to finish but has the stability to resist turning over when thrown hard. Brand new it will finish slightly to the left and beats in to finish really flat. I also love the feel of the Zero line plastics from Latitude 64, they wear in really well without becoming "broken" like some other baseline plastics do and has really good grip for a stiff plastic. I'm a big fan of how the disc flies, but not really the shape. Its pretty deep and slightly domey, which just feels weird to me. I really prefer a flat top on my putters so I eventually replaced this disc with the Aviars that I use now. I would still recommend this disc for a lot of people, but if you're picky about the shape/feel of your discs I would recommend that you hold this disc before buying it.

The Mercy is a putt and approach disc from Latitude 64. The Mercy has a very Aviar like feel in the hand, but it does feel a hair deepr. The Zero Hard plastic has nice grip, and will wear in like most other baseline plastics. The flight of the Mercy reminds me a lot of a P2, where it is very straight, but also stable. When putting in the circle, the flight would stay flat and straight, but outside the circle I started to see the fade. This disc is a great thrower as well, as it can handle some power and has consistent fade. It also has some nice glide which gives you some sneaky distance. Overall, Latitude 64 has a great stable putter option with the Mercy.

I currently putt with Zero Hard Pures, but I have experimented with Mercys and it went very well. They are a little deeper and seem to have better glide because of it. They do feel different, but they offer a similar beadless feel, like the Pure. I am currently living around 4,500 feet, so I may turn back to Mercys after I move back down in elevation and am looking for a little more stability (my Pures act stable enough up here).

The Mercy is a great putter for inside and outside the circle, as well as upshots and drives. They are very shape-able, and seem to find the chains very well. I believe that pretty much any putter (maybe even any disc in general) will preform inside the circle if you like the feel and have confidence with the disc. 

I look forward to running some more tests with the Mercy, Pure, and a few others to see what best suites my putting stroke. I love the Mercy and would really recommend trying one out. 

I have the McCabe signature Mercy's and absolutely love them inside the circle. I'm a spin putter and these release smooth and glide nice and straight.
