I have a NIB 16lb Shock Zone Pro for sale.  I bought the ball to be NIB.  The ball was new, but not in the box.  As a result, all I can say is that I bought it as 16lbs... and the pin is out approx 3 inches.  I don't know the top weight, but would assume it falls somewhere between 2oz and 4 oz.  I would be interested in trading it for 15lb equipment, or selling outright.  If interested, message me.
Thanks,
S^2
