I've always preferred traditional cloth mousepads. The smooth gaming pads glide too much with no resistance. Cloth has a little more tactile feel for predictable movement. And you want a large mousepad for serious business FPS gaming with a low in game sensitivity setting for precise aiming.
That's the pad I've been using for about 8 years now. Office depot use to sell them for $10 and I'd just buy a new one about every year. Greatest pad ever!
