Don't have a suggestion. I rode 23 Armadillos for may years and they were pretty good, but was interested in better performance. Tried the Conti Grand Prix wasn't happy, and the GP4000 everyone raves about--they didn't last. I found the Michelin Pro4 Endurance a good tire, but they don't exist any more. Don't know about Gatorskins or Schwalbe which seem to be the alternatives.
I actually switched to tubs (with sealant) (Veloflex Arenberg 25s) but I don't think that's an option with really poor roads.
