I run blazers on everything, haven't ever had any issue stabilizing arrows out to 80yrds. I'm not 100% convinced 4"duravanes stabilize any better than 2" blazers. Feathers are a different story, but duravanes, not so much. 323fps out of a 73lb Bowtech Destroyer 350 with 395grn Goldtip XT hunters, 425grn XT hunters out of 70lb mathew monster at 280fps, 50yrds is boring, 80 is a ball.
