yeah i still have mine and I use it often, First drilling was pin over ring with the MB out only 1 inch ball had sick length just glided past the head and midlane the it revved up made a quick turn and destroyed anything in its path great recovery when I got deep and with a few easy wrist adjustments could go straighter also, turn was easy control not snappy just very strong arc very late on the lane.

2nd drill is a little whacky pin is under my middle finger with the mb out about 3 inches this allows to play closer to friction and still get a quick reaction late on the lane. takes away from the ability to play deep but makes it a good drier lane ball very controllable with this  pattern
