My old cloth pad became too small for my new q3cfg (I use cl_mouseAccel "0" now), and I have decided to buy a larger mousepad.

Surfing websites with 115.2kbit/sec was hard (by mobile phone),
but finally I found a V2 version of XTrac Ripper pad.
It's 40*28cm and costs about 20$.

I think it's will be good for me.
