The understable discs I'm working with are:
Tursas, M4, Comet, Tangent, and Summit (firm)
Each one can be hyzerflipped easily and do what you are looking for, but the Tangent and Summit work best for me for whatever reason (plastic, weight, form, who knows). The Tangent with only a slight anhyzer release will hyzerflip and consistently glides up to about 275 feet before it gently sits down slightly to the right of midline. Dial it in and put some power into your throw and it lands dead straight. The Summit will do the same thing with an anhyzer release except it only consistently glides about 200 feet and can land even further to the right if desired. The Summit also hyzerflips with significant anhyzer release. It's very forgiving and pretty fun.
