UltraSonic....
Another sleeper! Not as dynamic as say a Hammer Doom...but very smooth and efficient in it's polished box condition. Clean as can be thru the heads, and destructive at the pocket!
It gets thru the heads so clean, you are very surprised at the demolition that it wreaks at the pocket. This is a ball I intend to have multiples of as well, because, I found that it was more consistent.....held a line longer.....and was more adjustable than some of my Brunswick stuff.
Took mine down to 800 grit, and found it to be an extremely reliable medium oil ball as well. Eventually took it back up to it's box condition cause of too much overlap with other balls I already had. (I had originally got it for the dryish conditions anyway)You'll be very satisfied with this ball.
