I use Michelin City tyres on the hybrid and Specialized All Condition Armadillo Elites** (700x23 - but they're more like 25) on the Condor, after a recommendation from @glasgowjim . He uses them on his audax adventures to good effect. Got the Armadillos from Myspokes, who had a good deal on at the time (£54 for 2 tyres) - but they don't appear to do them any more ...
** Elites are a bit lighter in weight than the standard Armadillo.
