I feel the same way, i watch my brother do this all the time and he never really gets distance. I know a big part of that is run-up and lack of technique elsewhere, but most guys should be able to strong arm a disc to nearly 300', he can get about 180', more on a fluke.
So i only use my middle finger on the inside of the rrim. I get great results and throw 350+ constantly. Do you think that if i switch grips i can get more distance or should i stick with what works? I tried to rip with my index and middle finger but i keep releasing it late and throwing it way right with out much extra distance (i did this and put my week old pro wraith in the middle of a pond)
