Love me some hyzer-flips; definitely my favorite shot in the game and one I was lucky to gravitate towards early - my weapon of choice, and it still is for H-Flips, is the Sidewinder. The angle of release and snap determines the flight, and with the right disc (typically something understable) you can hit nearly any line off the tee. If I want the disc to flip up almost to flat - get moderate distance - and fade, I throw it at a ~7:00 angle. I throw with moderate power at the ~8:00 angle, and I flip up to flat, glide for 325ft+, and finish straight or with a very slight fade. I throw with more significant snap at the ~8:00 angle and I flip up to flat, glide for huge distance while flipping up flat and slowly turning, and fade or hold the turn depending on the height. (This is all for RHBH).
Since discovering the SW, I have developed a disc at each slot that I like to use for hyzer-flip/turnover/understable role. For a putter H-Flipper I use the PA4 in 400s plastic (again, everything from hyzer finishes to full turnovers), for my mid I use the Meteor (beautiful hyzer-flip lazers, gentle turnovers, and pure accuracy), for my fairway I use an Underworld, for moderate drives I use the Sidewinder, and for the full Hyzer-flip distance I use the Sword.
