66GI is the golden ratio for me in London. So much easier to drop people when the lights change and they're mashing away trying to get up to speed. Much easier to skid control your bike too, or at least I find it that way.
I notice similar when I have a 46/30 crankset paired with 14-28 touring gears, spinny but found it so much easier to ride in London.
