I like helical. I did some offset straight the first time I did four fletch,and liked them. I did my first batch of four fletch helical the other day,but haven't shot them. Probably my favorite is three fletch helical. I've gotten arrows off the classifieds,and they managed to get way more helical on them than I had,and to tell you the truth I thought they looked weird flying. Mine just fly nice and straight,but I could really see the others turning. It may be a good thing,but mine flew just as straight,and seemed quieter.
