I concur with jkiser01. The TNV is a wonderful ball. I'm not sure what you are saying with "it doesnt move any better then any other of the top of the line balls". Do you mean that it doesn't hook anymore than other balls? If that is the case then more hook does not equate to a better bowling ball. I drilled one of these balls up after watching 6-7 other people using the ball, including Couch and Allen.
The thing I noticed with this ball is that no matter how its drilled and who is throwing it, the ball seems to give a consistent, controllable reaction with a solid finish. From my online readings, the TNVs that don't "hook" seem to be the trick layouts that lower rev bowlers drill up. Granted, I've only read about them, not seen them.
Granted this ball isn't for every condition, but I feel that this ball can help fill almost anyones arsenal. Maybe some of the proshop guys can chime in, but it seems to be one of the more customizable balls to date.
