Take with a grain of salt as I never skied the OGs, but I've got some "current" L138s, and they're fabulous. pivot, float, playful, great fun, can turn on a dime, don't have to. In deep untracked, I prefer them to protests and cease and desists (the two other best skis I've skied in the deep).
Only ever skied in deep snow, no idea how tf they do elsewhere, and don't care.
