Here's my results, with two differnt SU's.
First one, pin over ring, cg kicked right, weight hole. This ball I could play up the boards, and get some great backend. It carried very well, and drove hard all the way through the deck. The surface could be tweaked easily for heavier oil-lighter oil also.
Second one, pin under ring, cg kicked right, weight hole. This one is a beast. I've only used it at 800 grit for now. This drilling for me is very controlled, still has great backend, and hit's HARD.
I've had two Tsunami's, two Carbide+'s, and it out performed both of them a ton. For me, it covered alot more boards, was overall stronger, carried better, and was more versitle than both of those balls. The surface can be changed to cover many conditions. IMO I think it can handle for oil than the C+ and EU.
Just my .2 on my SU experiences.
