I have heard what he is saying about offset before. But as one guy in there said and as you mentioned it is OK on target arrows or field tips but does make a difference on B-heads. Some like to do there own test.... and others like to just take advice that others say works! Me, I like the forums with info and like saving time and money! I only like doing experiments if there is no info or I smell BS, usually the forums will have enough info where you can get what you need and not waste your time. I think he will be surprised when he does the B-head test.
