I've found a German vendor would ship a pair of Citizen Actives directly to my door for €36 (~$45 in today's rate,) so that ought to rule out the Tiogas - and everything else, for that matter. But, after all is said and done, it might be cheap for a reason, even if it's a Schwalbe. Could it possibly be better than the Tioga, which costs more than twice as much? Have to buy before I try!

So, seeing as how there seems to be no shortage of love for the Supreme, how come Schwalbe discontinued our size?
