mine the pin is 2 7/8" from the cg. Pin is above the ring finger and mass bias is a little right of thumb (right handed. The CG is a little left of the pin/mb line so the ball has 7/8 oz side weight, no extra weight hole.
I bowl on synthetics with strong backend and outsides (stripped daily. I'm able to keep the speed up and not have to hit the ball much. The BW gets down the lanes and has a killer hard arc in the backend. The carry on the ball is unreal. The ball also has more area for me. I've only bowled 8 games with the ball in my summer league so far but have averaged 245 for the 8 games.
Two thumbs up for the Black Widow.
