hey, i'm going to pick up a small squeeze lock knife for my balance bcd, should clip right on but i'm wondering whether to get the stainless or the titanium for a few bucks more. one dive shop i spoke too said get the titanium because it won't rust if you forget to wipe it off, the other said get the stainless because the titanium isn't as strong and doesn't reflect as well (not sure what this meant). thoughts? thanks!
