Bought this ball as a 2nd drill and I've come close to 300 multiple times with this ball more than any other (on a house shot). Drilled with pin a good inch below ring finger (I'm RH) . Predictable, heavy roll continues well through the pocket shot after shot. Not for heavy oil but nice on medium oil. Picks up on higher friction lane surface but not jumpy. One can bump in and ride oil line a little longer before letting ball encounter friction to get a nice blended reaction.
Just bought another one of these to keep in my closet as a backup.
My Hammer Diesel hooks more than I actually anticipated. I put the pin up in between my fingers and the CG kicked out just a little with no weight hole. Its also the strongest ball I will keep for my house shot arsenal. I remember practicing with it and I was standing almost as far right (I'm LH) as I do with my Gauntlet. There's no question about the power of the Diesel. You will get A LOT of ball for your money on this one!
