Double Thumb Drilling Technique
« on: September 20, 2008, 07:09:33 AM »
Is there a time when using this technique that you will drill out the mass bias?...I say NO due to 1/2 shift of the base line and the drill angle change..

Anyone used this in their ball?...How did it work for you?...and more importantly please answer my question
