Sean,
I am just now starting to experiment with shooting vanes off of the shelf with a longbow. Have gotten some good advice from people and have shot some of a friends vaned arrows with very good results. Have been shooting aluminum and some wood arrows always with feathers, because I was told that is all that would work off the shelf with longbows and recurves, but now after more than a decade I start to question that. Switched to carbons and full metal jackets about a year or so ago, with very good results. But am always having problems with feather wear and tear off. I live and hunt in the southwest and wind and shots longer than 20 yards are part of the terms that you face here. So, for hunting pronghorn this year I plan on using 500 FMJ with a 125gr. broad-head cut to 29", this is going out of a shrew LB at 53#. I am going to have 4 arrow fletched with shorter vanes and see how they fly. I hope that this will offer flat shooting arrow that can handle some wind and still deliver a punch. So go have fun and shoot all different kinds of arrows and fletching combinations, see what you like, Then after you find what you like, keep looking because there may be something else out there. Have fun.
