I've gotta say that the stiffer the better on carpet. Didn't the TC3 fill up every A main slot in stock touring at Cleveland last time? Look at Easton's results there. However, on asphalt a little flex seems to be the best way to go. One thing for certain, it certainly makes a car more forgiving and easier to drive. If you're going to see someone struggle outdoors, it usually isn't with a Schumacher.
