Wilk, I' ve never tried fingers out of a WB, so I can' t say from experience. I don' t use sights and I' d be looking at a blob of whiskers instead of what I' m shooting at if I tried it. But I have seen a few posts on various forums where guys are doing pretty good with them and shooting fingers. There aren' t many left nowadays that shoot fingers with compounds and not many of them shoot a WB, so it' s going to be tough finding someone to give advice on it. This is one of those things where your friend will just have to bite the bullet and give it a try if he thinks it' s something he wants to do.
