What plastics have you tried and which are your overall favorites?
Champion, Champion Blizzard, Star, Starlite, Echo Star, KC Pro, R-Pro, DX;
Z, X, Elite?, FLX, Pro-D;
Proton (soft and regular), Neutron, Fission;
Opto, Goldline;
Signature Line;
Lightning's base plastic...Hi-Flex?
And what is it that is used for Instep's discs?
For putt and approach, Signature Line, and then R-Pro are favorites.
For mids and drivers, the best I can say is that I generally prefer Star/Starlite, though it is good to have some Innova in Champ; I haven't used X or FLX all that much yet, but prefer them so far for Discraft, though only marginally so over Z; I definitely prefer Neutron or Fission over Proton (I look forward to trying Plasma); and the seeming virtual indestructability of Opto makes it a hard choice versus Goldline.
