What's your favourite gear ratio?

I've just switched my Genesis Flyer frame for a Pearsons frame, running 48 x 16. Not sure if it's my imagination but I seem to be spinning out a lot quicker on the new frame, so I may need to make a change. Would I notice a difference running, say, a 49 x 16 to slow my cadence down a bit?

Keep 'spinning out' during the winter, you wouldn't like to get caught on a heavier gearing with headwind and snowy roads as your new friend.
