Really great ball and man does It have a great backend motion. Laid mine out 50 * 4.5 * 30 and it gets through the fronts very well, and really takes a turn off the end of the pattern, Must have!!

Had been looking for a sanded symmetrical solid since the lane beds & oils were changed in my local bowling center. When I saw this pop up I immediately placed my order, had it in my hands within 48 hrs & drilled it up that day, pin above bridge, CG toward my PAP. This ball! Smooth, not jumpy but miss right and hit the dry and it's gonna snap back hard! Very controllable, not too early but early enough to be affected with over & under much. Ball was very easy to read and very consistent, so I was able to stay ahead of the transition and keep my carry high. Fewer corner pins than I had been experiencing on the local patterns, so that was a plus as well. Gonna be a bit before I put this one down.

The Royal Diamond is a great control ball! When the lanes are hooking, this ball will be great for when you need to control the huge amount of friction. With 2000 grit, this ball comes out of my bag first and gives a very nice round shape!

I can't wait to throw this bad boy, EVERY SINGLE diamond ball that I have seen thrown has been absolutely fantastic! Expect nothing less from this piece!
