I don't know, but to me this craze of one over-stable disc in each category (putter, mid, fairway, control and distance) seems to be causing more harm than help to the average player. I play with one guy who was actually really good with nothing but Aviar P&As and Rocs who started chasing the OS game and his game has gone to hell. He has lost all his finesse and he's constantly chasing more OS discs to "fix" his new problem.
I used to bag a Drone, then found there wasn't anything it did for me that I couldn't use a Banshee for, then I dropped the Banshee for a Max weight Eagle-X. One mold, very versatile and with a few in different states of wear I've been good for the last few years. I throw short spike hyzers with it and at times I'll even throw 150 FHs with no problem, just have to learn the mold.
Yeah, all the elite top level players seem to have lots of OS stuff, but, they are elite! Not the average pro. I think of pros that I will never be as good as and who's game I admire and none of them regularly use meat-hook mids or putters.

If they can get by without them, what makes the average chucker think he needs them?
For the last few months, I have been playing rounds with nothing but;
Aviar P&As, Rocs, Eagles, Gazelles, and depending on the course I add a Sidewinder and an Orc, and my scores have gone down!
But I'm more of a finesse player who only throws around 330ft, so take what I say with a grain of salt.
I'm not saying an OS disc doesn't have it's uses, but to me, this over-stable everything craze is selling lots of discs, but not helping a lot of peoples game.
