I use a Deathadder mouse, and I find that when I am playing at my top speed I end up gripping the mouse harder, and my little finger sort of curls under the edge of the bottom of my mouse. It doesn't exactly lift the mouse, or anything, but I normally have that finger gliding along the mat in contact with it, and the extra pressure from a tight grip causes me to press into the mouse where it touches the mat, since it is lifted from the mat a little bit by being on Teflon feet. After enough time, this becomes pretty painful, but I can't seem to find a way to grip the mouse and get as much control as I do when I hold it my normal way. Has anyone else had this happen to them? Did you get used to it? I've gotten so used to it that I sort of just don't even notice it, but I was wondering what others' experiences might have been.
