All that flew right over my head lol. I do build my own arrows but all I do is buy raw shafts, cut them to length, install inserts, fletch and start shooting. I pick out the best shooting arrows to hunt with and practice with the others. I do however always test my arrows that i'm going to hunt with to insure they are straight, spin true and hit where i'm aiming. That's about as deep as I go.Do you fletch your c0ck vane parallel or perpendicular to the flat line isolation of the shaft?
