In gusting winds in field practice yesterday my Sword flipped each time in headwinds. I needed about 4 degrees of initial hyzer for a flip to flat. If i released flat in a lull in the wind at the throwing place and the wind hit the disc in flight it flipped that same 4 degrees. Moderate winds. I have a while from my previous Destroyer throws but if memory serves it is less susceptible to gusts. If a broken in Pro Destroyer flips it comes back maybe a tad later than my disc. I also used a King and a Z Nuke and my Sword fades earlier than both it is also consistently significantly shorter on average and in max D. From the descriptions of others we either differ in form (i don't have super RPMs) or mine may be less HSS and possibly a little more LSS than your discs.
Describe your Sword...I'm throwing a cobalt blue 175 VIP and a black 175 tourney. Both are fairly domey. Because the plastic is so grippy on both my Swords and the grip feels so good to me, I'm betting that I am getting more spin on them than I do most other drivers. It feels effortless to me, and I think this means I can spin it and get results without having to really arm it. I have to arm discs like the Nuke and the Boss because I just don't get as good of RPMs on the widest rimmed discs. The Flow is similar for me in this respect. I could also do similar things with FR and E* Destroyers, but not the other runs.
