I searched for the answer to this as I am sure it has been discussed ad naseum, but I could not seem to hit on the right search phrase.

Anyway, I want to start fletching my own arrows. I use a WB rest and currently shoot 4" vanes with a right offset (these were set up by the pro-shop I bought the bow at). I would like to experiment with 2" Blazers as I have been reading they work better with the WB. What I was wondering is if I should use the same offset I am using with the 4", or use helical? Specifically, I am looking for the best setup to use with the WB. I haven't had any problems with the 4" and the WB, but would like to try something new.
