Weight is one advantage, at least for us hardy cold water divers who use thick wet suits or dry suits with real underwear. Besides, you only have to buy the adapter as you already have the back plate and harness. OMS makes everything in stainless steel, and with two back plates and the single tank adapter plus a nice heavy steel tank it takes care of the buoyancy requirements as well, again assuming you need that much weight due to insulation etc. That gets a little expensive, at least up here, but I think it's worth it comfort wise. It helps my heavy feet to a great extent, not having any weight around the waist. I've always wondered how anyone can need ankle weights, but I digress. Is there a picture of the Sea Tec single tank adapter on the web somewhere? About the original question regarding the stability of this set up: It's stable. The grommets on the wings do deform a little if you tighten everything down, but after a couple of dives there is no need to retighten any more. I'm using LP steels and it's the only way I would dive them due to their weight, hence need for a stable attachment. Egil. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
