My Hoyt Dealer gave me a few Blazer Vanes to try on a few arrows when I picked up my new bow in February. I put them on with the same offset I was using for my 4" Gateway feathers. I was so impressed with the arrow flight thru the B2 Biscuit I ordered a bunch more. Several of the arrows have been shot 50 times or more and have no warping or marks on them. I haven't tried them with my Tekan II or my Spitfires yet only on fieldpoints.
