I've got them. They fly like darts. Broadheads and field tips impact the same. I'm using Shuttle T broadheads. I did fletch them with 4 of the mini spins, but I don't think it matters 3 or 4 if everything else is right. A good quality arrow is the foundation. My Carbon Tech Whitetails with .001 straightness are fantastic. I had one arrow from 18 that didn't want to cooperate. It wouldn't even shoot in the group with field points. I had the longer fletchings on my other bow and arrows(Beaman ICS Hunters) The Speed Hunters are much more durable to me. With the regular Quick Spins if you had one slap with another arrow they got messed up.
