ICEMAT+ mice?

So i've just tried them all on a blue icemat
Deathadder is nice - top measured speed ~ 3m/s so it's almost impossible to skip with it. I haven't experienced the problem which chelmianin wrote coz my icemat is new and i don't use it, but that is rly possible ;o
Ikari optical is even better - top measured speed IS OVER 5m/s, moreover it's perfect control speed so there's zero negative acceleration. Couldn't make it skip moving it over the pad like crazy :D However this mouse is probably not the best choice coz of 1 very important problem: the buttons are VERY sensitive, they fucking press themselves if you pick your mouse up and then put it down, especially on hard pads like icemat. I have mouse3 binded as /kill and EVERY time i put my mouse down i selfkill :X same for mouse1 & mouse2. That's why i don't use it
mx518 - the skipping speed is about 2,3 m/s that's pretty high, but still this mouse is the most easily skipped out of these 3(that's only on Icemat, overall this mouse is the most difficult to skip with). Also i noticed that both mine mx518 which i tested are rly weird on most surfaces: when you move it to the right and then to the left with the same speed it very rarely comes to the same point :S the difference is small but still very noticeable. It's like the mousespeed to the right is a bit faster than to the left. However on some pads like everglide titan fnatic & qpad ct they both work like a charm :S Check yours pls and tell me, might be that it's only mine(although i dont think so) If your mouse doesn't have this problem the best mouse to buy is probably mx518 coz you're used to it.
