Thanks again for the info Flecc, I'll look into those tubes & try to track down the elusive 47 if necessary: do you think it would smooth out the bumps better than a 38? Or not much difference? That one can (according to schwalbes specs) run the 47 at lower pressure (45 psi vs 50 psi "minimum" for the 38) may assist in that?
If so & m-plus 47 isn't available, would you recommend any other tyre for "near" flat-proofing? The conti contact security looks to be similar design in theory, but I haven't looked into its availability, let alone in wider sizes! I'm not very reassured by all these kevlar/nylon/vectran "belts", are any good?
