You have heard it from the performance riders on this forum, Hermes & AJ both have a balance that is hard to beat.
Once you are in that "normal" weight range, focus more on strength & health.
I find that my riding improves when I am 10# lighter but my attitude does not, I get cranky because I can't enjoy treats or an occasional beer or wine. Strike a balance, we will never be on the TDF circuit.
