joeabroad:My new Worthington 100s weigh 34 lbs. empty. I haven't been in the water yet with them (and won't until next summer, alas), but I figure that in terms of removing weight it will be a wash--taking 4 pounds off the belt, but adding 4 pounds to the tank (assuming that the average weight of an aluminum 80 is 30 lbs.) The real plus is the extra air--even if I only fill them to 3000 psi I'll be getting at least 10 percent more air than I would with aluminum 80s.
That's the out of water weight though. You need the in-water buoyancy numbers to see how much weight you can drop.
Going from an AL80 to a PST E7-100 I dropped 4 pounds initially, and then maybe another 2 after that.
The PST is close to neutral empty, compared to the AL80 at (usually) around +6
