So today was the big day where my new BP/W got in touch with water for the first time
I used it in a pool for a long training session (including underwater kit removal and all this stuff). I must say, I absolutely loved it! You basically don't feel it at all underwater, the trim was amazing, the deflation works so much nicer than with a jacket BCD - and that all even being naturally significantly overweighted (SS BP, full tank with rash guard in fresh water).
Can't wait to dive it in Australia in a couple of weeks. Thanks everyone here for convincing me to go for one and to
@cool_hardware52 for a really fine rig!
