Judging by the other reviews, seems like there might be some inconsistencies in the production of this disc, and mine is no different.  Mine is definitely much less stable than its indicated numbers.  For reference, I throw a Destroyer as my reliable overstable driver which gets me about 300' thrown flat, so I shouldn't be able to get any turn out of this disc, yet turn it did, and pretty significantly, too.  In fact, in the field it threw nearly identically to my D3, usually about 10' shorter as it has about a point less glide.  And it did fly consistently, I'll give it that, just not as advertised.

I'm actually going to go ahead and bag it in place of my D3 (which is getting a little squirrelly), because I actually really like mine.  It's a great looking disc, and a pretty cool conversation piece (not a lot of folks have even heard of Yikun), and it does fill a needed slot.  But I can only give it 3 stars because I can't strongly recommend a disc that may or may not fly completely differently than mine.

The Twin Swords is a very cool looking disc. It feels nice in the hand and seems like it should bomb.

That is where the positive attributes of the disc end. The flight numbers are comically wrong. The Twin Swords has a LOT of high speed turn, and any hard throw will have to be made hyzer to keep the disc from corkscrewing into the ground. Within about 10 drives I knew this disc wasn't going to work. The only throws I made with the Twin Swords that were relatively decent were downwind.

The Twin Swords glides OK, but doesn't penetrate very well. Its so flippy that you can't really bear down hard on it without violently turning it over. Distance was mediocre. I honestly didn't have one drive with this disc that impressed me even an iota. This thing flies like a Mamba or really flippy Tern. However, it lacks the glide and distance of both. The Twin Swords wasn't coming close to keeping up with stuff like Terns and Shrykes for distance.

HUGELY lame and disappointing driver here. The only people I'd recommend this to are those who throw under 350'. Anything longer than that and you're going to turn and burn this thing.

The disc itself seems poorly produced, like a cheap knockoff of an Axiom or MVP product. I'm thinking the long term durability of the plastic would be poor.

Bottom line upfront: GREAT Disc!

Nicely engineered. However, Construction (fit and finish) is a bit lacking but easy to fix...

?When I got the disc I did some field work, It felt good in my hands and the release was incredibly smooth. However I was initially under whelmed with the flight. it was fluttery seemed to have OAT no matter how clean the release.

When I got home I noticed the Tab in Slot of the overmold was not flush. I worked the rim massaging out high spots and got the overmold seated much better. I went back out to the field and OMG what a difference! strong fade minimal turn very consistent flight and this thing goes far. After the second field test, I put the disc in warm water again massaging the overmold slot and tabs and got them completely flush.WHAT A DIFFERENCE

Next day I took the Twin Sword (169g) on course. Hole 1 is 367' fairly open, I normally throw an Innova Beast (159g) consistently 325'-350'. I threw the Twin Sword 10' passed the hole and about 5' to the left of the basket - easily my best drive on that hole (thought I had a shot at glory for a split second).

After a full round (another 9 holes using this disc), I had great results - Hyser; Anhyser; tailwind; crosswind; head wind, all good predicable lines.It fought wind much better than I expected. Turn was minimal; fade was late, strong, and consistent. Also this disc is NOT too nose angle sensitive and as such is a little forgiving and very easy to throw.

Glide is nice maybe a touch over 5; Fade is a strong 2; some turn with the crosswind (Obviously) and just a little turn when thrown flat into a small head wind.

I picked up this disc because of how cool it looked and the flight numbers! I have in the Tortoise Line, it looks fantastic one of the prettier discs out there.

After some field work with it I though it would be good addition to my bag as a less stable driver. Initially I felt it was a 12/5/-2/1.

I don't throw it that often and when I do it is usually on wide open holes so it's not getting beat up much. It has now become too understable to trust, pretty much only a roller disc.

Warning. This flight numbers are super misleading. I thought I was buying a stable distance driver; what I got was a roller disc. Brand new, it flies more similar to a Daedalus, which is like a fast sidewinder.

That being said, I bought the full color version with the angel man on it. It's a sweet looking disc, and I'll probably keep it in the bag to show it off, but only as a roller, or stand still backhand hyzerflip disc.

This is the perfect disc for players who want to maximize their distance but aren't power throwers. I don't recommend it for advanced or pro men though.
