One of the guys at my local shop told me that a Whisker Biscuit will tear or at least wrinkle the standard 4" fletching on any arrow. I can certainly attest to that. Per his suggestion, I've switched to 2" Blazer vanes. I sense that I've lost a little speed, since the Blazer arrows don't penetrate my target as deeply, but I'm not refletching arrows after 5 shots. A tradeoff I'm willing to make.
