I can compare/contrast the Shout to the solid Storm Natural, so happens I was just practicing with them today.

I was hoping to play pretty close to the ditch (short pattern being used for the next two weeks in the sport shot league, at a different house). No idea what they had put out on that lane but I was able to play out to 3 or 4 at the arrows with the Natural (normally impossible for me without doing something drastic to ball speed and hand release).

The last game I decided to switch to the Shout. I rolled the first one at the same alignment and it held pocket, but I could tell it didn't want to. I moved in to 6 at the arrows, much better (with the Natural it would have been very difficult to carry from 6, I really wish I knew what I was bowling on!)

The layouts and surface are both different, but the thing that strikes me most is the difference in shape. The urethane ball seems to hook early which to my eyes looks like it will be a bad thing, but then it just sets up and goes in at a milder angle than the reactive ball. Meanwhile the Shout is still very predictable when it does make it's move, and has more recovery. I like them both, I would say that I want the urethane when I'm trying to grind out a 200ish score on difficult conditions, where the Shout is (at least in my hands) more capable of keeping up with a higher scoring environment when the lanes are tough but not TOO tough. Not to say one can't throw up big numbers with urethane, if it matches up well you sure can.
