Similar to my experience (as posted earlier) - the only difference is that as soon as we went into OW for my check out dives, my instructor went to his BP&W (he only uses the jacket type in the pool - saves his personal kit for OW due to how much damage the chlorine in pools can do to gear).
Because I have a long body the cummerbund on a jacket tends to be way too high to do any good and the jacket slides up. Also I found that when air was added on surfacing, I found it very difficult to move and breathe properly.
Saw him in his BP&W (especially at the points where my jacket type was trying to strangle me) and immediately wanted one. Changed to it on my fourth dive (post check out) and loved it the first time I dove it.
