Once again, thanks for the input. It looks like I should have had the Balance in the poll, as I believe it would have topped the results.
My LDS has one which I tried on out of the water, and it definately feels good not be to encumbered by all the other bits and pieces.
They didn't want to let me take it out in the water (understanderbly) so I've been trying to find someone locally (friends of a brother-in-law's instructor who know guys that work at a diveshop, etc ,etc) who has one that I take for a test drive, but it doesn't look like its going to happen.
But I think I'll be taking a drip to the LDS tonight and make the plunge anyway.
(And to cross-reference another thread, there has been one available on E-Bay, and its a lot cheaper on LP. But the LDS has been extremely helpful, and spent a lot of time helping me out. So they get my business)
