If they meet your own requirements for proper flight, then shoot them. Many, many variables affect what is going on with a set-up. Very similar bows with similar draw weight and seemingly identical shelves may tune the same arrows totally different. Your own barshafting and BH validation are plenty of justification. Many times I feel who ever delivers the most effective response becomes gospel when, in fact, it may only be a well delivered rationalization or guess.
The bottom line is we must at some point perform our own validation and have faith.
