Whew, the last time I did 150 miles on 32mm tires, it just about killed me.
One thing that should be pointed out is that a quality low rolling resistance 32mm tire is probably close to the rolling resistance of the average 25mm tire.
However, take the commuter tires, touring tires, etc in the 32mm size, and they can be BEASTS.
