I'm currently diving a singles setup and am looking to move to doubles, but I'm not sure how much liftI need. The only immediate change to my gear will be double AL80s in stead of a single AL80, tank bands, an isolator (using left/right modular valves already), an additional first stage (HOG D1CW), and the new wing. I dive with 4lbs of lead on a belt with the single AL80. I'm currently using a DSS large steel plate and a Torus 17 wing. The Torus 17 can float me at the beginning of a dive with an additional 2-3 lbs of weight; any more than that, though, is pushing it. I'm diving a DIR setup, with a full 3mm wetsuit and 2mm neoprene pocket shorts.
My (unresearched) guess is that I should be adding an additional 6-8lb in hardware (first stage, isolator, bands) and have an additional -2lb to +3lb swing due to gas in the second AL80. By my guess, that puts me needing an additional 10lbs of lift at a minimum...and more in the future if I am carrying more gear/stages/etc. Is that close to correct?
Based on all that, would the Torus 38 be enough, or should I go to the 42?
