Flip side: Yesterday. Fresh water (49F BTW...). First time this BP/ can/ scrubber/ suit/ undies/ bottle/ bailout/ configuration. 4 mm crushed neoprene dry (dry at least at beginning of dive, but that's another story
). 19 cf AL bottles. Std. Meg can w/ small radial scrubber & appropriate spacer. Just one 30 cf AL bailout. Carbon fiber BP. Trim pretty good. Took a whopping 32 lb lead added a couple of lb at a time to get negative! (I've been told before I'm full of hot air, but this was ridiculous!!!).
