They preform well with both my NAP spitfires (expandable) and the Razorbaks (fixed) but they aren't the best in the durability dept. I'm constantly having to straighten them out because the wrinkle easily. I don't feel that they're worth the $$$ either. I've got a set of Blazers on deck for when these Quick Spins crap out, I'm just hoping I can get through the season without having to refletch everything.
