The DefCon II I drilled out had the following pre-drill specs:
Gross weight: 15 lbs 6 oz
Top Weight: 3.46 oz
Pin Placement: 2 1/2 inches
I chose my favorite drilling to see wah tthe ball would do...4" stack leverage. This put the pin at 1:30 to my ring finger and about 1/2 inch away.post drill specs showed 3/4 side and 1/2 finger and a small hole located 5 1/2" right and 1" down from grip center.
Lane conditions and performance:
Shot#1...our house shot....oil to 32, buffed to 38, basic top hat shot, 1 day old backends. This ball had me a tad bit confused on this shot. Perhaps I had been anticipating more hook. This ball slid way further than I expected. It hooked about 5 boards less than my identically drilled Eraser. A slight shift with the feet and the ball got into the pocket and just destroyed pins. The carry is exceptional with this ball. high, light or flush this ball scattered pins everywhere.
Shot #2...league shot, another house....fresh backends with a christmas tree pattern of oil to 35 and buff to 43. I could play this ball very well if I kept it in the track area. I could not swing this ball, it never made it back.
Shot#3...open bowling shot, Saturday afternoons with no oiling that day and leftovers from the night before. Now this ball shined through. A solid heavy roll thru the pines and a nice smooth arc into the pocket. Was able to play a conservative swing of 12 to 5 while lining up about 20. I could go deeper but the ball seemed to finish harder with the 12-5 shot.
Overall a good ball for drier lane conditions or perhaps more oil if you turn the ball harder. The core is very dynamic but I don't think the coverstock kept up with the core.
