66" is not pathetic at all, a great gear for long rides with some climbs. <this coming from someone that can't climb for toffee.
I wouldn't change it. You could maybe try low 70s" for a flattish ride like out to cambridge or southend, but I wouldn't be tempted to risk mashing your knees to bits with a big gear. Save the massive gears for riding on a track.
