Although I do wish I had bigger gears (the stock chain rings had slightly higher gearing than what I have now).

If you still have the original crank, you might be able to just swap the rings (assuming the new crank has the same bot pattern). I may go back to the higher gearing as I lose weight myself, which is part of the reason I went with the same model crank. However, if you don't have the old rings, it is generally just as expensive to replace 3 rings as it is to get a brand new crank with the rings that you want.. I don't know why, but it seems to be the case.

Your other option would be to get a new rear cassette with smaller gears -- that would get your gear ratios back to where they were before, and cassettes tend to be cheaper than crank rings.
