Given the amount of miles you've done / will do get a custom Titanium from Waltly. It can then be specc'd to exactly what you want and will be cheaper than most options. I can't recommend them high enough. My one fits 35mm with guards or 40mm without.
Titanium doesn't appeal. Seems the worst of all worlds to me - expensive, not much lighter than steel or Al, high failure rate, unrepairable, unrecyclable, etc.
