I shoot straight fletching and have plenty of success in the hunting fields.

Around this time of year, I see lines of people at the pro shops having stock arrows cut to length for bows capable of sending them downrange in excess of 250fps. That's all fine and good, but these things come pre-fletched at what? 2 degrees offset? I've arrived at around 7 eyeballed degrees of right helical for my Gold Tips to eliminate planing entirely.

Out of curiosity, how much offset does everyone use???

I just don't see 2 degrees as being remotely adequate for stabalizing broadheads out of most of todays speed bows.
