In all seriousness though the amount of weight lost from removing a brake and brake lever is negligible. Your best bet is a new wheelset with low rotational mass. If you are just looking to improve your riding experience, don't worry so much about weight, focus on comfort. Look to upgrade the contact points: saddle, pedals, and handlebar (all the while ensuring that you have a good fit).

Edit: IMHO the single best value in performance enhancement is in going to a clipless setup.
