I am thinking of trying some of the blazers on a dozen goldtip prohunter shafts. I was wondering what size should I use shooting a fixed head such as a 100 grain 3 blade muzzy, or G5 montec? How much do they weigh as well? I usually get my arrows fletched at a right 4 degrees, and was wondering if this will work with these vanes? I have been using duravanes for years and like them alot, but I was thinking of trying something different just for the heck of it. Thanks to all.
