In general, a LONG pin with a high top weight. Almost impossible to swing the CG and be able to drill enough out to make the ball legal. Keep the CG in and the pin would be so high that the ball would roll real funny. Also, a pin right on top of the CG would be bad for many folks.
For the ball with a mass bias, if you had a funky spec where the cg ended above the pin and one would have to invert the ball to drill it may be more than what some pro shop operators could handle. Also, if in a mass bias the Pro CG or Pro Pin stuff you see out of Storm with some real funky spots could be very difficult for some to handle.
It is all about the buyer, what the buyer is looking for, and what the seller has. I throw 14# and would be VERY interested in the USA Gold ball, but I would need specs with between a 2 and 3 1/2 pin and between 2 and 3 ounces of top. Anything outside of those specs makes the ball bad FOR ME. However, someone else may love a super short or super long pin.
