Actually it's the other way around. If one floated, then they were a witch. If they sunk and drowned, they weren't.
As for the OP's question, titanium is pretty light compared to steel. And the finish on those bars don't look like any aluminum finish I've seen. So if they are lighter than a comparable length of steel handle bars, then I would go with titanium.
Titanium isn't magnetic either. But I don't know if that includes when tested with neodymium magnets. Stainless steel is weekly attracted to regular magnets and strongly attracted to neodymium magnets.
