I have one data point for Ti, which does not bend much before it breaks, on boats...
The big boat I race on had titanium stantions for the lifelines. While racing at Block Island one year, we launched off a wave and the crew hit hard against the lifelines. Two stantions snapped, and one bent.
We no longer have Ti on the boat.
Some materials just don't work in some situations. And I am a huge fan of Ti for bikes, rides like steel but light like Aluminum.
