RE: Fletching
I like Duravane Predators.
Go on great, low profile, .5" high, 2" long, and they are extremely stiff. Haven't shot them with broadheads yet, but I'm sure they'll do just fine.
Put them on with super glue gel and you shouldn't have any problems with them coming off.
That's the set up I use and I love it.
I shot AAE Max Hunters for awhile, liked them really well, but they seemed to come off the arrows easily (on target pass throughs especially).
