The 35's seem great for flat or rolling terrain, and riding in dirt and gravel, but I'm thinking twice about using them again on very hilly or mountainous paved roads (pretty much all of my riding these days). Anyone else notice slower climbing speeds on wide tires?
So not to be obvious, but if you're riding paved roads, I'd hazard a guess that 35s would generally always be slower whether climbing, descending or going flat (albeit less so here) than some narrower tire. Maybe look for a happy medium somewhere between your 23s and 35s ?
