Great boot. I used to have the SLXs with CO2s and Cartels. I switched to the Grails and the Malavitas. Great combo. Really comfy. Obviously, it's not as responsive as the SLX/Cartel setup, but it's still more than responsive enough and much more playful. If you want a slightly stiffer boot, I hear the Shaun Whites are the way to go. I will be riding the Grails for a long time. They are comfy with plenty of response. I hear that the 2011 will be a bit stiffer than this years model.
