I've got an older FRX and some 11s. All work well. With the new ones, spend some time adjusting them before you get to the mountain. Then, just click and ride. You probably will need one more adjustment sometime during the day.
I love mine and recommend them to everyone from student to my teachers.
When you're on a lift that you know, you can clip in the back foot while going up. Then, you ride off the lift past the snow sitters. Sweet!
