Blazers aren't magic. They are just tough as hell, no ripples, easy and fast to fletch due to their short length and I've never found another vane that shoots flatter and more accurately with field points and expandable broadheads like the NAP Spitfires. That's good enough for me :-)

BTW, it was the only vane that I could find to withstand the abuse of a Whisker Biscuit rest when I was shooting compound bows.
