Reread your post, glass. There's no "little hyzer". I went absurd with the Diamond reference because, regardless of how much both discs turn, THEY STILL TURN! They still need to be thrown with hyzer, regardless of the angle, to go straight.
The Tangent has some turn. Whoop-de-doo. I'm not denying that it could be a very useful disc. I saw potential from it in the few throws I had with it. I'm not trying to hurt anyone's feelings. MVP is still a good manufacturer with some great products, but there are discs that fit the description of what the OP wants. Many people have mentioned that there are great options outside of Innova. The OP never said he was open to other manufacturers. The Tangent is not the disc to recommend here. I'm sorry to pee in your Wheaties.
OP, you should try a Legacy Ghost in Gravity plastic. It turns but will go straight if you throw it with hyzer. Sorry I completely ignored the details of your request.
