Drilled this ball up last week. 16#, pin is about 2". Placed the pin under the ring finger, and kicked the cg off to the right about an 1" or so from my center of grip. Works out to be about a 5x4 for me, no weight hole needed. Out of the box, this cover looked too dull for me, so I put some polish on it before I drilled it to help get some length, due to the shorter pin. First off, even with the polish on this ball, it still read the lane a little earlier than I anticipated. The ball revs up nice, and for me, gets decent length and has a very strong arc to the pocket. Definately an aggressive piece. Last week in league I struggled with carry the first two games. I had drilled this ball that night, so I decided to throw it the last game. I pulled this out and shot 279, leaving one solid ten pin. This week, I decided to start with this ball, and wound up shooting 279-279-279 for an 837, just a few ten pins. The ball hits very well, and when in the pocket, the pins wind up in the pit. If the shot is a hair less than flush, this ball will definately throw the lumber around and carry the dime. I was surprised how easy this ball adjusted to the lane break down. I had expected it to jump immediately once the oil started to disappear, but this ball held the line all night. Slight changes in hand position, and a small move of the feet, and stayed in the pocket. For me, this ball looks like, and reacts like the El Nino 2000, which I really liked. Overall I think this ball is much stronger, and definately worth the bang for the buck. An outstanding piece for the price, and will now be my benchmark ball.
