Going to ride about 8500 miles in January 2008. 7500+ miles will be on tarmac. The remainder on varying types of sand and gravel.

A TKC80 rear should cope with about 5000 miles and the front should do the whole trip. I'll be riding at speeds up to 90/95 mph on the tarmac. Not heavily laden, but I'm told that overheating inner tubes could be a problem.

Tubeless are simpler. Both have reinforced casings. Inner tube puncture could be easier to fix (just replace) by the roadside.

So the question is tubed or tubeless? Your views and advice would be welcome.
