The original 15lb Agressive I had was drilled a little too strong for me (I drilled it before getting the specs).  However, it still rolled extemely well.  It was 4 1/2 with the pin below the ring, 1 1/2" above midline at a 60* angle.  Weighthole on the axis but pitched .5" away.  Box surface. This produced a ball that had a ton of early flare but unlike other balls that generally flare this much this early, it didn't burn as much and it still had some continuation.  It was limited when the heads started to go and there was some carrydown.  However, it was a great ball to read the lanes with and it really blended out the pattern.  It didn't work well when I had to have lots of angle through the fronts or had to get in but on fresh patterns and wet/drys it worked well.  Carry was phenominal.

The current one is 16lbs.  Pin is 5 1/2" on centerline below fingers. 1 1/2" above midline at 70* angle.  Weighthole is 2 1/4" inches below PAP at 3" deep.  This maybe one of the most versatile balls I've had in a few years.  This layout/cover matchup is perfect.  By going with such a weak pin (but on a ball with a strong core), the ball is very stable through the first 30 or so feet.  But then with the flare increasing hole, the ball just flares extremely hard in the backend part of the lane. This allows me to keep the ball in box surface but still have a ball that will read, recover but still be smooth.  It also allows me to use it even as it's burning up and not loose hit.  I've used this ball on several different surfaces.  Wood, 15' of guardian, 60' of guardian, HPL 9000s, Anvilane, etc.  It performed beautifully on all of them.  I've also used on it various patterns.  Long, short, medium and somewhat light with head oil.  It's been used from the 3rd board to 5th arrow.   It responds extremely well to hand changes.  

This is a great ball and a must in anyone's bag looking for hook, control and power.
