I have a couple Discraft discs in my bag because I found them (unmarked), threw them, and I like them. I am otherwise totally Innova. I have every reason to not like Innova after some business interactions that went badly, but I am too lazy to learn all the names and associated flight paths of other discs. I do not throw much of the wide rim stuff (speed 11 on up) and that is where most of the new molds are.
I am fine with my Aviars, Rocs, Firebirds, Orcs, TL's and Sidewinders and sticking with them. My game does not suffer from not having other molds, but rather from inconsistently throwing what I have well enough. If there is a disc that could consistently take 2 throws off my round, I would love to know about it.
