I have 1 season on my 15lb Diesel Particle (which I got off ebay NIB) and had it drilled stacked leverage with the pin just below the ring finger, and later added a small weight hole 2 1/2" below my PAP on the VAL. I took the surface down with a green scotchbrite and hit it with a very light coat of Beans Sauce. This ball has been awesome for me, both on slick house shots and on tournament shots, and seems to always turn the corner, and compliments my Phenom Unleashed when the PU is not strong enough. Very reliable.
