RE: feathers or vanes
I have used both and prefer the flight characteristics of the feathers. I did start using the quickspins and they work very well for me. I use a fall away rest so contact is not an issue. I do alot of back country and late season hunting in some brutal weather and can't carry both in with me so I opted to use the quickspin vanes as they cover about everythig I may encounter and still give me great performance.
