thanks for all the help. I am in no way blaming the broadheads for the poor arrow flight, i just know that some dont shot good out of surtent set ups. that is why after trying several reputable heads i am here asking these questions. I am shooting 100 grain heads and my arrows are cut to 28 inches, in the 340 spine. againg thanks for the help. Would it be a good idea to go with the 4 inch quickspins next time or are stay withthe 2.25? also would it make a diffrence switching to a 125 grain head?
