I'm not going to take the time to fletch arrows with a jig so I really like them too. Have used them for a few years and had no problems.
Were you shooting field tips? I would recommend comparing the size of broadhead groups to the size of field tip groups if you haven't already done so.
I wasn't actually. However, I don't have a target I can shoot BH's in to. Would a Rage 3 Blade practice tip suffice or should I try the real BH's?
Just shoot one of them. I really like the Quick Fletch QuikSpins... I did find the twisters shot great until I used fixed broadheads, then they were all over. That may not be the case with Rage but I would definitely check. Just shoot a broadhead... then shoot a couple field tips... there should be no difference. Find out if the broadhead point of impact changes with different arrows. If you really want to know, use a large fixed head.
Love them! Won't pay someone to put vanes on an arrow ever again. I was surprised how much they improved my groups, with and without fixed broadheads. The leading edge of the cresting tore up a little on an arrow I shot through one shoulder and into the opposite shoulder blade on a mature doe, the arrow was toast anyway. I've had complete pass thrus with no sign of any damage, just had to wash the blood out of the grooves in the twisters. Where do I get the bowhunting.com ones??
