won the ball a day giveaway for June 14th, got the package yesterday, and opened the box and there were TWO machines in it

difference specs on them, both 15lbs 3ozs, one has 1 3/4 top weight and a 1-1.5 inch pin, the other has 3 1/4 top weight and a 2.5-3 inch pin
what im wondering is what would be the difference in reaction if i drilled the balls the same
also am thinking about keeping one OOB and the other dulled with green scothbrite and clean and dull
what do you guys think about this?
and Rick, didnt get the video done in Texas so have nothing for you yet, gonna try and get my PAP and Axis Tilt info for ya sometime next week
