Newbie- I have never heard of Light Parker- is it a brand? I can tell you my philosophy about clothing for skiing (and mountaineering, too), for whatever it is worth.
I believe strongly that multiple layers is the way to go- no single heavy jacket, but rather several layers of insulation and outer weather protection. The versatility of a clothing "system" like this allows for easy changes when the weather changes, and comfort in the spring and winter, sun and snow. My outer layer is Gortex xcr (the new more breathable version of goretex) with no insulation whatsoever. I use it when it's snowing or windy, and may dispense with it in spring conditions. It has lots of venting, too, so I have not had any problem with excessive interior humidity when I'm really active. In climates where you don't need real imperviousness to all elements (I bought mine for summer mountaineering use, too) the new "softshell" garments give more breathability, but are still repellent enough to shed snow, especially if it is dry snow like here in the intermountain west- look for Scholler Dryskin fabrics. Many of the goretex competitors are good, too- I used to have a Triple Point Ceramic jacket from Lowe Alpine that was great, and Marmot Membrane is supposed to be really good as well.
For warmth you add layers of fleece (or down when it is really, really cold) underneath- it breaths well, dries in no time and wicks moisture like crazy. There are a zillion choices for different kinds. I would think about the goretex (or whatever oether fabric) shell as the outer layer of protection from wind, snow, rain, etc, and let the fleece layers provide the warmth. BY the way, I use the same thing on my lower body- thin fleece pants with goretex shell pants, rather than insulated ski pants.
