Strange Question

Ok this may seem like an odd question, but I was just curious with some precision adjustments being made in post production, what kind of mouse do you use? Optical or do you use Laser? Is there really a difference in the Laser that makes for smoother movements?

I had been using an optical trackball, but just switched to using the Graphire 4 tablet. I like it very much, despite having to get used to using the stylus.

Logitech laser or optical, can't remember which one is on that PC. Makes no difference because I often enter numbers rather than use the sliders in ACR.

Many here also use a Wacom Tablet.
