I have it. Got it the day it came out and while my skills don't lend themselves to giving a full review on equipment anymore, I'll say the same things about the ball I said on another forum ...
* It is truly a different ball than anything else on the market right now with the possible exception of the Purple Hammer, and it's a good bit stronger than the PH is.
* I really think it's the next step in evolution for modern urethane coverstocks. It takes the best of urethane and mixes it with the most usable elements of a mid-strength reactive.
* I also have the 900 Global Infused Badger and it's a much different animal than that. Not only a completely different core design (not to mention asym in the UC3 vs. sym for the IB), but the cover on the UC3 is going to be usable on a much wider range of lane conditions.
* The best analogy to this ball, outside of however similar you might find a Purple Hammer, is to go back in time to the old Visionary Slate Blue Gargoyle, except the UC3 is many, many degrees stronger. I mention the SBG because it was the first (and to this point, one of the rare few) urethane balls that actually would hockey-stick a bit in the backend naturally, without being touchy. It's hard to get angularity out of urethane as we all know, but the SBG came by it naturally and so does the UC3. Except the UC3 can handle a lot more oil volume.
For people who like urethane, you either need the Purple Hammer, this ball, or both. Otherwise you're leaving a big gap in your urethane arsenal. And between those two, I would pick the UC3 based on what I've seen so far. Two straight weeks in league for me now that every game with the UC3 was over my average, and I was able to stay with a single ball longer instead of having to do a lot of ball swapping.
