I drilled my Attitude Shift 2 1/2 x 6
Its a pretty weak drilling. I drilled it exactly the same as my Special Agent and my Secret Agent just for comparison. The best way to describe the Attitude Shift to me is a much stronger Special Agent. The first game in league play I had 11 strikes for a 266, yes I chopped a spare with my new Ice Storm. I was bowling on a pretty high volume of oil, playing 15 at the arrows to about 7 or 8 at 35 to 37 feet down the lane. The ball corners hard at the breakpoint but not angular very smooth but very strong. If you are looking for a strong ball to add to your arsenal I would suggest the Attitude Shift. If you do get it and it is to strong the Attitude Shift takes a polish with ease.
