I have been doing this for years,regardless of the berger hole.It really is irrelevant to me.I always set my arrow up as low as possible.(I did try to shoot a vital bow gear ultimate fall away a couple years and it HAD to be set high)It did fine for a hunting bow but there was a noticable drop in forgiveness.

I wasn't able to get the 08 whammy as low as I like on my new Alphamax but it does go through the center.Many complain they can't get them that low on the BT.

My 07 Whammy is so low on my Xtec that my sight is just about out of adjustment.Man that thing is a shooter,but so is the AM.
