Can anyone chime in on this? They are priced similarly, but offer different advantages. The Aeris is environmentally sealed, so may be better for future cold water dives in NE and may result in a longer life. The Zeagle, which is not sealed, received a perfect score (20 of 20) on Rodales, which I believe is based mostly on breathability. For comparison, the Aeris received a 12 of 20, but has been reviewed highly by other publications. I know I should try first, but I am living in the desert right now, with no LDS, and I want to purchase my own equipment for a month long trip to the Caribbean in September. Not that it matters, but I have decided to go with a BP/Wing for the BC. Oh, and I am not really interested in the ScubaPro products. I know they have an excellent reputation, but I have a personal aversion to their marketing tactics. Also, I think I may run into serviceability problems with Apeks (and I want to buy American if I can). Thanks in advance.
