My stick is always handy.
I used the new setup both days last weekend, at Crystan and Stevens, and I have to say it was AWESOME. The boots don't feel much wimpier than my alpines, the skis were really nice and easy to turn, and the whole ski/boot/binding combo was so light it felt like driving a sports car compared to the SUV of my alpine setup. And even at a resort the walk mode is a nice bonus for clunking around the cafeteria and the parking lot.
The Dynafits take a little more effort than alpine step-ins, but it'll certainly be worth it for the reduced weight in the backcountry.
