However they come

. I'm not real picky to be honest. I prefer a slight offset, don't really care what direction. Like Arthur I also prefer feathers. You can shoot them straight fletched and still get some spin to them. Most of my arrows are a 4 degree right offset though I think.
With a drop a way I don't mind a helical. I do not like straight vanes though, not even for target shooting. They will work, but I just like some spin to my arrows, its a mental thing I think.
