I think the most important difference between the 2 is the camber. Blend has a little early rise (on the newest model) and double time gets its name from its double camber. If you're looking for powder and soft snow the double time isn't going to do you any favors, it was designed as a park ski. With the stiffness and huge camber I bet it carves and charges well though, never tried it though so can't give you any first hand insight.
