...or maybe a 44T? Check the aforementioned Sheldon Brown Gear Calculator. It can give you the comparative "gear inches" for your current set-up vs. what 42T or 44T will do. If that comparison doesn't mean anything to you, you will just have to experiment.
I initially changed our custom Dual-Drive Fridays from 42T to 46T chain rings, so I had some idea what the 53T to 48T change on the Pocket 8's would do.
