Stick with the same weight....you may lose your timing with the lighter ball. When I switched to 15# from 16# 3 years ago, I lost my tming for a few months just from the different feel. Going down a # in a spare ball you throw here and there is ok, but not a ball you would carry and possibly use here and there.
