I don't care for blazers because they are high, stiff, light weight and not as advertised, they total in weight a lot more than they claim.
My biggest beef and the one that matters is flight. Using a 100 Thunderhead the blazer being so light and possibly because of it's short length cause my arrows point of impact to fluctuate to an extreme. My arrows fly at a flatter trajectory with vanes totaling 25 grns. Feathers do the same as blazers.
I like the 4" savage duravane in all red.
Just bought some Beman bone collector arrows with blazer from a guy and shot with points and T Head, arrow point of impact dropped too much and then I remembered why, too much FOC. Thunderheads tell it like it is. Once they grab air it just keeps grabbing more. I can typically use one pin from 18-25 yrds. The drop with blazers couldn't do it, I'd be out of the zone before 25.
