I throw Innova drivers and Discraft mids. I like the Discraft series BuzzzSS, Buzzz, Wasp, Hornet because they all have very similar feel in the grip. Once I got really comfortable with one of them, I can throw them all the same way and get different flight patterns. I think Roc throwers do the same thing with different levels of wear or all the numerous variations on Roc molds. But that seems way too complicated, and difficult to replace when you lose one, so I never tried to learn it.
