a hyzer-flip shot has several advantages over anhyzer shots. But don't think that you have to learn to throw one to get good, some pretty good players dont' use them much (and some use them a lot).
1st, why throw a hyzer-flip instead of an anhyzer? Because hyzer flip doesn't really turn right until it flips, so you have a much shorter distance where a disc is heading right. Less chance for the disc to run away. Especially into a headwind, an anhyzer drive is very hard to control, even more so if you have to throw low.
2nd, hyzer-flip technique is pretty close to the tecnique needed to throw your putters and midranges a long way, so is a good method to focus on when learning how to throw. This is as opposed to throwing fast, overstable drivers already turned, a habbit that can get people to screw up their midrange game.
3rd, hyzer-flip shots go very far, squeezing the lost drop of distance before petering out.
4th, knowing how to flip up a hyzer also gives another element of height control, in that it is easy to throw a driver nose down but have the hyzer action lift it naturally, so that you get heighth without the risk of stalling out and hyzering away, or throwing an anhyzer high and risking it turning and turning.
The disc I think is easiest for learning a hyzer flip shot is a DX shark.
just my two cents from someone who is trying to learn quickly and realized that the game got a lot easier when I decided that a hyzer flip-type shot would be my default throw, until the hole situation forces a different shot.
