RE: Pros & Cons of Diamond vanes & FF vanes
Flex Fletch is a great vane, very tough. I used them for years and really liked them a lot. the only reason I use the AAE/Easton ones now is they are easy to find & if you buy the AAE ones they are cheap, hold up well, and for the most part good quality.
I will say I think the Flex Fletch is a better vane if you have no fletching contact with your rest.
