So, FWIW the only sidewinder I've thrown is a 9/10 DX I found uninked in the local pond; and the only times I could get it to flip up without turning and burning or crashing into a bush or tree off to the right were long downhill shots to the right. So there may be a gap in our power levels. However, I do tend to hyzer flip more often than others I play with and IMO plastic type is very important for a hyzer flip disc. I want my flippers to be dependable. That means i either want them to start out and hold onto their desired stability or beat into the sweet spot to reach it. Unless my plan is to beat something relatively stable or slightly OS to flippable (for the sake of mold minimization/cycling)I usually prefer premium plastic for this slot since it will hold the flight characteristics longest. My Z Buzzz SSs are my most called upon hyzer flip discs and they hardly change at all as they beat, I have a 7/10 that just seems more workable now; I can muscle it to finish gently right if I care to. IME Base plastic Buzzzes get flippier than Z Buzzz SSs. I have a beat to hell(4/10) Pro-D buzzz that does nothing but turn hard right, even on a 90 degree hyzer it will finish anhyzer (Currently trying to beat some base truths to overtake that slot so I don't have any regular buzzzes in the bag [elite X Buzzz SSs would solve all my problems]). On the other hand, If I want something longer in a hyzer flip shot I will use a beat 6/10 3rd run C-line FD that can now finish slightly right if thrown flat(my distance fairway) OR I could power down My D-line FD on an extreme hyzer OR I could whip out a fresh out of the box P-line FD if I am looking to start breaking one of those in for more US duties. I actually preferred a fresh P-line for this shot( felt more controlled, stayed closer to the ground, but it didn't stay at that stability more than 3-4 tree hits. Basically, what I'm trying to get at is this: If you build a bag based only around discs that will do exactly what you want[out of the box it could create confusion, frustration, and/or the need to consolidate molds later on when those discs are breaking in past the point you can utilize them for the shots they were initially bagged for. Not that it's a bad bag building strategy, just something to be aware of. Especially when considering the US side of your bag. It's for this reason that 'my favorite disc for a good long hyzer flip' is not necessarily an under stable mold. My favorite flipping mid is, but my favorite flipping driver is beat to perfection for that shot.
