As far as the Autos go, I love the strap technology. Fast in and out, the strap definitely gets tight enough and has good control. I had a pair of 08s that were stolen a few weeks ago and just picked up a pair of 09's to replace them. I wasn't really feelin the chinsey looking toe strap on this years model. The ankle strap also barely has any padding on this years model. They are going for light, but I want comfort and control.
I don't think the 07/08 models had the Harshmellow but the new ones I picked up have it so I'm eager to see if it makes any difference. I do have the T1 boots with Harshmellow and I can say they are really comfortable after the initial break in. They are really big boots though and barely fit in the Auto Bindings.
