I do not use the beeman arrows but will throw my 2 cents here anyway. I noticed that the WB was causing the cock vane (white in my case) to ripple after about 6 shots. Having been schooled in the TM hunter style rest I always nocked up with the cock vane down, so I thought that was the problem. I switched to cock vane up and ran a new set of 6 arrows through a round of shooting and still had the same results, white vane rippled? The WB did not care how the arrow was nocked up with regards to accuracy either.
