Mine is roughly 3 5/8 by 3 5/8 (PAP past 6" over), the pin is about an inch above the finger line.  It's in whatever you get by putting 300+ games on an OOB ball on mostly synthetic lanes and practically no maintenance.

It worked well for me on medium to medium heavy lanes, playing between the second and third arrows.  A few times I moved in deeper and slowed the speed down but I'm not as comfortable.  I used it in my PBA league this summer on the Shark and was happy.

It's a real strong ball, looking back I wonder if it was too strong for some of the conditions I tried to use it on.  It was my primary ball for a long time without much of a backup.
