I use stright offset myself and have always been told to turn the fletch into the bow, I don't think it really matters. I started out with stright offset for clearence of the rest and never saw reason to change. I now use the muzzy zero effect and could change if i wanted as there is no clearence problem with that rest. I also have had a JoJan multi fletcher for the better part of 20 years, works fine for me.
