Have any of you guys that build your own arrows noticed any appreciable difference in accuracy and number of culls between regular GT II's and GT II Pros? If so, is it enough in your opinion, to justify the price difference? This with the understanding that they're all accurate enough for white-tails.
It really depends on the bow you are shooting and the f.p.s. Certain faster bows will benefit from using the better arrows,while in other bows there will be little if any difference.
Squaring both ends of the raw shafts will get good results too, and it's worth doing if you are having issues. You can also square the brass inserts.
When you cross the 375 f.p.s. threshold you will need all your arrows near perfection.
