My cordless Trackball is great for most gameplay. But using zoom and sniper rifle or that percision mortar shot just take to long to get lined up. I had to ball extra balls for it cause of the abuse it takes as I slam it to the desk over missed opportunities. The ball gets a dimple (small) but noticable. Since I've used a trackball design now for 6 years or so it is so difficult to get use to a regular mouse. I'll keep trying as time permits...but like yesterday playing arena tribes, I was a newbie all over again. After a couple maps I had to rip it out and put my trackball back in and show those kids that this old fart has game. Didn't work!!!
Thanks for the ideas for the mouse...I'll start looking for something to buy that can help the glide but as Wid and Doc indicated if the lag continues and is normal with a cordless mouse, I might have to try the wired one.
