One thing you might want to consider is the repair side of things. Where you live, can you or somebody you know (maybe a shop) weld and repair titanium? There is nobody in my area that can. If you can't get the pipes repaired if they ever break on you, is it still a good choice for your area? Most places can repair steel and aluminum pipes.
