I have 32mm Grand Bois Cypres extralights on another bike, and agree that at the right pressure (about 55 psi front, 60 psi rear, in my case), they feel almost as good as a 42mm tire, at least on reasonable pavement. And the added advantage is significantly lower rotational weight, which I can definitely feel. But for any kind of rough road surface, the lower pressure of a 42mm tire over a 32mm tire makes a huge difference.
