What speed disc are you throwing 300 feet with? It sounds like you are ready for any faster speed disc. I personally like Innova drivers ie eagles, firebirds, thunderbirds, wraiths and destroyers.I'm throwing at best a little over 300 feet. I'm looking to add a little distance. Wondering what disc I can throw that is around an 8 or 9 speed that can go just a bit further.
I would say to just focus on your form and the distance will come.I'm driving with a photon right now. It's an 11 speed. I've tried a star destroyer and a wraith and they just crash down after about 250 feet or so. I'm throwing my hex that far.
