Indeed. I actually ride 68", slightly higher than Oli, but the general rule is don't go over 70" if you want to do actual hills or longer rides.
I've been settled on 48:17 (74.1 GI) for years now. I dont attack the proper mountain roads on this (I have 41:26 for full on ascents). But I use my fixed for the most part, for out of town rides of 50 - 100 km. The word undulating doesnt even begin to describe the landscape up here.

IMHO its a matter of taste, and muscle type.
