I rememberd an old trick I learned when I played more desktop games. Some mice have little plates in them to weigh the device down a bit. Turns out you can extract them and have a lighter, often smoother experience.
On top of that, the last time I took mine apart, I lost a spring in the click-wheel mechanism. Turned out to be a blessing in disguise which I repeated (voluntarily this time) to get the resulting effect. When you scroll the wheel, there is no more resistance or clicking sound to the motion. Once again, a smoother and lighter experience.
