I got my Ultra Zone about a month ago, and I absolutely love it. I've only been on the Brunswick bandwagon for a year or so, so I can't really compare it to another Brunswick piece, but for me, the Ultra is very comparable to Columbia's Power Drive Pearl. One could also argue it's close to Storm's Thunderstruck Pearl, although the Ultra is more rolly than the Thunderstruck.
It reads the midlanes unbelievably, but hitting power is definitely not sacrificed. My particular Ultra has a 2-inch pin with the pin under the bridge and the CG slightly kicked. I'm a high-rev, high-speed player (450ish RPM, 19ish MPH), but even so, this ball will start up in the midlanes and finish strong. For me, I can't get deep and open the lanes with this ball (obviously), but if I want to play the track area or even a little right of it, the Ultra is the first ball out of the bag.
As far as carry is concerned, as long as you're far enough right (or left for you southpaws) with it, you'll kick the corners out all day. However, if you're too deep, you'll leave marshmallow corners all day long. If the lanes make the ball want to go too long, you'll ring corners all day if you're too firm with the speed. From my experiences anyway, the Ultra is highly speed sensitive when the lanes are tight, but if you have any friction towards the gutter, you'll be styling.
Hope this helps!
