What was wrong with your Qck? I'm using Qck+ (also owned Goliathus Control, which according to most is the better than speed), and I find it to be near flawless. However the +edition is supposed to be thicker than the normal one if I'm not mistaken, and could possibly have other differences as well. The one I used was Tyloo edition. Anyhow, I can recommend XFX Warpad. Thick mousepad, super comfortable, and generally a great size even for low sens users.
