RE: NAP QuickSpin Information
Yes i was using vanes... And how much speed you lose depends on how much of a helical you use to...You dont really need it with the QS's...
Not sure about the speed difference if you switch from feathers..I don't use feathers... Try shooting through a crono with you faether arrows and shoot 1 through with a QS arrow and see what the difference is..See if anyone at the shop you go to or even the owner for that matter has one made up with QS's that they would maybe let you shoot through the crony that may be simialr to what you use now as far as length and weight wise...
