Can anyone say balance? Too much weight either front or rear will have negative effects. You want to balance your loads across the frame - consider that your body is pretty much centered, maybe with a bit more weight on the front axle than the rear, depending upon your riding position. Adding some weight to the rear (starting from just your body on the bike) might actually provide better overall distribution of all of your weight on the bike. From there...a little more on the front, a little more on the rear...a little for Santa...a little more for Santa...

If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
