Simmer Down, not that it isn't avaliable but I've never seen it on the boats I've dived off of in Cancun. My BadLSDeep:HUH? here to!!! what has saltwater to do with the potential use of nitrox???? you need to help me along there!
otherwise, yes i would agree titanium and high O2 levels dont mix very well. i would also agree that titanium is more a "gimmick" for the diver with toooooo much money that has it all. if you need to lower your equipment weight, there are better points to start.
