I had my first outing on my NX2-AT last night and all I can say is, FANTASTIC! So much easier to kick-in, and I was literally kicking-in right off the lift while still moving and down the mountain. Had multiple people going "What are those?!" as I go riding by while they were sitting. The wife was a little jealous, so it looks liek the Prima's might be in her future.
Piece of advice for making kicking in easy, make sure the highback is completely extended down. If its up a little bit, the strap wont be fully extended and makes it tougher to kick-in.
