duravanes, blazers, feathers, flex fletch. Been shooting all 4 at once with fp's and notice little difference out to 50 yrds. And they are on 2 different arrows 5575 hunter GT's and 7595 XT GT's. Have tried the blazers and duravaneson both with BH's and the 5575 hit consistantly 3"right of the 7595's @ 30. It must change I would think at different distances. They also have 3 different nocks. Shot at an orange from 30 the past 2 days and they all make juice if I release right. I've even used 2 different tips and there's no difference. I'm sure the story would be different with BH's but it's kind of fun just being carefree and shooting around with just anything. Feel like a kid. I'll still hunt with the duravanes.
