Yes. The new Neox uses aluminum in the plate instead of last year's steel. It reduced the weight-per-pair by about 1.1 lbs. It was noticable to me when carrying my B5s from the locker room to the slopes at Copper the first couple of times. It may have been a little noticable when blasting through really choppy windslab at Breck, but my own personal jury is still out on that.
