Kinda hard to give advice with such little info(preference of glide etc.etc.) plus it's a bit harder to suggest to RTS than it is to FPS due to the way you use the mouse.
Previous post on the artisan pads and a small review of the
shiden-kai with pics Hein=rougher(some have mentioned aggravation on their wrist due the surface), Shiden=smooth, and Shi-Kai=slightly faster glide than shiden. Apparently difference in the glass amount of glass.
I'm really not sure if I should suggest them as most of the information comes from FPS gamers. Plus they are generally more expensive than what is normally sold. Though considering your an RTS player and generally RTS use a higher sensitivity; the small one isn't as expensive and it's size is around a tiny bit smaller than the Icemat-2. Only real negative I can see is the fact you can't roll them, well if your careful you can but it can damage the material and if your planning on going to LAN you might need to keep it inside a some binding or protective cover.
There's a lot more mousepads out there but you'll most likely run into the same companies all the time, not that they are all bad just some aren't what people are wanting to use nor should be recommended for that particular game or way of using the mouse. But then again a lot of people ask too vaguely and they just get the general lot rather than the specific one.
