With the release of the TOS lungs it's on hold, my new HH Extreme should be here by Friday so I'm going to dive a few rigs side by side to judge WOB between rigs and BMCL, TOS and OTS lungs, but what I found is as follows: 1) you can get great WOB in most positions (with BMCL's) if you spend a hell of a lot of time and money making the "perfect" enclosure but the issue is that the best enclosure for the lungs adds about 4-5" to your profile and is a real pain in the ass to build, so the jury is out pending this weekends test dives sorry for the delay but I just figured out how to access the "Notifications" section.
how is your boat project going?
