I fletched three arrows with them over the weekend.I followed the directions and put a slight right offset on them.I'm shooting a Mathews lx,cx 300 shafts off a trophy taker at 299 fps.They grouped right with the same shats that were fletched right helical with 4 inch vanes.Due the the expense of these vanes,I didn't try to shoot a group but they seemed to shoot a little more consistantly than the regular vanes.It wasn't a big difference but I do think they shot slightly better. I also shot several arrows with 100 gr slick trick's,90 gr muzzy's and 100 gr 3 bladed muzzy's.Every single arrow went exactly where it was intended.I didn't have one flier.Distance was 30 yards.I get simolar results with helical but these definately seemed more consistant.Other than the price,I think they're a winner.
