RE: Helical or straight vanes??
I have never had a problem with my Bitz Dial O Fletch and AAE vanes, using the AAE Fastset gel on carbons. I let them sit about 5 minutes per flech, usually while watching a TV show. The helical from the jig stays pretty well. Like I said, not near what I have seen with 5" feathers and traditional equipment, but seems to be more than enough to spin the arrow.
