Good suggestion, tks.

In four years of commuting I have terminally damaged two Gatorskins, one Marathon Plus Tour, two Conti Town and Countrys and one Panracer Pasela. Obviously it would be cheaper and less hassle if I could extend the life of some of these.

In the meantime, I am curious to try the Marathon Plus. Besides rolling resistance Schwalbe claims low rolling resistance as well. There's a couple of more off-road/world tour oriented tires I'd like to try too, but I cant fit wider than a 32mm tire under fenders on my old Voyageur.
