Slonda's correct....not many places have bp/w for you to try out. When I went from my back inflate BC to my bp/w set-up, I was a little worried about what would happen if I didn't like it. But after all the reading I did, I only found one person (out of tons!) that bought a bp/w and ended up not liking it after diving with it multiple times, and then opted to go back to a traditional BC.
I, however, am not with that one person....I LOVE my bp/w and would strongly recommend that set-up to anyone, even those diving strictly recreational (like me, for now). For less than $400, you can get a great bp/w (insert DSS plug here
), and I would be almost certain that you would love it!
