I like 1.5 - 1.75" myself. I've even been wanting to try some of the 26 x 1.35" Schwalbe knobbies if I get out on a mostly dirt trip.
Toured earlier this summer part paved/part dirt roads on 1.5" Michelin Country Rocks. I like them cuz they're cheap. Put Mr Tuffy in and they're tough also. I brought a folding 1.95" IRC Mythos semislick for backup. Also cheap @ $15 and light as well.
