Post subject:  thumb, finger hole depth = ball reaction

Beings balance hole is no longer legal. I don't use them anyway. In laymens terms

1) Ball reaction having a deep thumb hole.

2) Ball reaction of fingers drilled deep

3) Ball reaction if one finger drilled deeper than the other.

I am plugging and moving the thumb hole about 1/4" down/longer span on a ebonite phenom solid symmetrical. No balance hole. 4" p2p, roughly 30 deg val as it is now. pin is 1.5" above and right of ring finger.
