Are you kidding me? You need to fix your form. I throw the volt 400-425 and have had zero problems with it being crazy flippy. It turns a little but will fade back perfectly straight in front of you. when I start putting them out to 450 they do make a very subtle turn through their flight until the last 10%. I release with a very small amount of hyzer on those throws.
Not a thing wrong with my form. When I can throw the Saint right next to a Volt and have the Saint be more stable... it's not me. I went and rewatched Mike's vids too to see how my experiences looked next to his. I find it hard to believe he and I are throwing the same disc.
