I just bought a pair of LTE's from halftilt off here on ns. Have yet to ski them, because they haven't arrived, but I'm stoked to try them! As for powder, try skiing on those, and then demo something more like 115 underfoot to truly appreciate how awesome powder skis are in powder. The LTE's are definitely not meant for powder, and the tips will probably dive on you, but if you backseat super hard it might work! Haha no but seriously try powder skis. Your life will be so much easier. Also what kind of powder skiing are you doing? It might be good to consider if you be hucking huge drops and bombing steep lines, or if you're jibbing and boosting through the trees. Nimble vs straight line performance is a big deal. With that I could probably help suggest what you'd wanna ski.
Spark notes: if you don't have to, don't use them for powder
