I've had an Ultimate for about 9 months and it's a great ball. It is sarting to loose its abilities in the very fresh oil, so I've smoothed it out by putting a 2000 grit shine on it. It still hits and works superbly for me.
I added a scorching and so far it's just too much. I'm going to change the surface tonight from the OOB finsih and try it at 1000 grit. We'll see....
P.S. Both balls are drilled exactly the same... exactly the same pin length, pin position, and CG position.
