I've skied the PLPs and they were SO much fun, LTEs are still on my hit list (skis I want to ski) but I heard nothing but good things about them. They're lightweight, bamboo core, snappy, poppy, soft but solid underfoot, low swing weight, and extremely fun (at least that's what I've heard about them). I'd say go with the LTE cause they are slightly lighter and probably a bit more fun.
havent skied the plp, but i love my lte's...i think they are a perfect flex for just about any situation. tons of pop, can land backseat and wont wash out, stiff enough under foot to haul ass without getting squirrelly...if you can find a good deal on the lte's take it, if not go with your deal on the plp's and im sure you'll love them just as much
