Schobs:
I've never shot feathers, I do however shoot 2" blazers thru my WB without any problem. I think I'd continue to shoot the feathers till they quit grouping for you (don't know 'bout bow season where you are but here the season is basically over) since the off season is here. When they fail to group get you a fletching jig (offset or helical), some wraps and some blazers and refletch (if ya can't get them refletched for free at the shop you bought 'em at). Thats what I'm doing as my regualr vanes get destroyed. It's alot of fun and it gives me something to do. Just my $.02.
