Hmm, plenty of options to consider, thanks.
My route, FWIW, is 9.2 miles. About 3 miles is on good, surfaced cycle tracks, 5.5 miles on tarmac roads and the rest on a bumpy bridlepath.
I like Land Cruisers, but need something more puncture resistant. I know Marathon + is a way to go, but I'd rather have something lighter, if possible.
