honestly I have got one drilled and another on the way.  I have to tell you if you dont have the ball speed its not a good ball.  I mean you will see a very big reaction.  Its good through the mid lane and then the back end its going to flip hard.  I would suggest though that if you have a slower ball speed that I wouldnt use it.

GREAT BALL

AS FAR AS PIN AND ALL.  ANY OF THE NORMAL PINS OR TOP WEIGHTS.  THIS BALL WILL FLIP HARD IF IT TOUCHES ANY DRY BOARD.

I refer to slow as probably as around 10mph .  I think most who throw this maybe have around 15 to 20.  I mean if you throw it hard then it will work for you

to be honest, I havent seen a person yet say anything bad about the pins.  I mean the normal "pins" maybe 1" to 2 are the best.  But everyone who has any of these pins says they are awesome.  I am not sure about anything beyond 2.5 since most that are sent to us are in the before stated pin lengths.  Sorry if this is vague

Mine is drilled 3-1/2 x 5-3/4 x 2-1/2, with a 4" pin. After throwing it a game or two it seemed to read and move a little earlier than I wanted. I took the cover up to 800 grit and got more length and a hard turn on the backend, not flip but a very angular turn more than I had expected have moderate speed 15-15.5 with a med to med high rev rate, the WMB is very predictable with a smooth angular motion at the breakpoint.
