I've got a diamond back 3 years ago and it expired due to wear and tear.

Got another copperhead, sens ratio is slightly different but i prefer copperhead's touch. feels more balanced as diamondback makes my wrist grind against my mousepad.

Thinking of Habu, diamond back 3G, Death adder or lachesis.

I hope someone can tell me the difference between Optical laser and Optical Infraed mice. the pros and cons and most importantly, surface issues.

I'm using Razer eXactMat Speed/Control surface.
