Nubo, I'm shooting 3" feathers out of the Patriot at over 300 fps and they shoot and group great. I may even try them for hunting with my mechanicals. BTW, my arrow length is 29" and I shoot a right helical on them (at least as much as you can get out of a 3" feather on a carbon shaft). As a bonus there is virtually no feather "hiss" with them either. Try the 3", I think you'll like them.
