In my opinion you need to spin an arrow with a fixed blade broadhead. That requires helical or offset fletching. I would be concerned with sending these vanes through a WB. There is no way to guarantee that the interaction between the whiskers and vanes is identical shot to shot.How do you know it wont increase your groups? I would want to back up my claim before I called someone out. I can't comment to the accuracy of a WB because I have always shot a trophy taker fall away.
If Johnb is shooting groups within 1" of bullseye at 50 yds, I'd say he should continue doing what he's doing. I don't believe this is a right or wrong, black and white issue.
