I have the 38's. They're ok, but I prefer the Supremes. Rolling resistance is ok, but not great. Good grip. I've never had a flat on them, though iirc bicycle rolling resistance shows them with lower puncture protection.

I might try the 37c Panaracer Pasela. 380 grams.

I used to have the 26" Big Apples which were good, but heavier.
