What do you prefer the best mousemat of mx518?

Well, I've been searching in these days for an preferable mousepad for the mouse, Logitech mx518.

I bought an Steelpad QcK, but after 2 months waiting I'd rather cancel than keeping my money away to buy after it is delivered.

So, now I ask to you, (also the guys without an mx518, Razers and mx510 opinions welcome), about what the best mousepad of an mx518 should be.

I was thinking about an icepad, qpad, steelpad, well, post your opinion!
