I have a Razer Ironclad. On top i use a Lachesis 5600DPI with Soft Mousefeet.
I really like that, because it's very smooth motionwise and it has sort of a anti acceleration (i use activated mouse acceleration). That fits my mouse movement very well. It's very hard, too, so i think it won't easily wear down.
With my predecessor pad (had the razer vespula before, used the control surface), i was very disappointed, because it had heavy wear down after ~3weeks; the pad before the vespula was fine, that was an everglide ricochet, i had that for 5 years.
But the ironclad is the best i ever had!
My summary is something like that:
-mouse acceleration activated
-very low sensitivity
