The local bow shop was giving their pitch on these arrows they carry by easton https://eastonarchery.com/target/6mm-hexx/... I am currently shooting the gold tip velocity xt arrows. They said I would gain up to 10fps (possibly) because of the weight of the easton arrow. I'm shooting 318 @ 70lbs @ 31" draw. Does anyone use these arrows and if you made the switch to them how much did you go up on your speed?
