Well now, this brings up a question in my mind. I was shooting 4 inch vanes, but mounted a Whisker Biscuit and had to change. The veins would not hold up. I switched to Blazers and have been in love with them ever since..... Just took every arrow I have to my pro shop to have new Blazers installed.... AND now someone says duravanes is the only way to go with a W.B.? Is this true? But I love my blazers, right helical... they fly good.Am I missing something more accurate?
