I am 5'9" 185 lbs and own the 2009 AC30 in a 170. This is a great ski for the type of conditions I normally encounter (east coast, groomers, hardpack/ice). The AC30 is more of a 70/30 type ski with a front side bias. That said to give you a recommendation depends on the type of conditions you encounter. Since you are from Vacouver, I assume you are skiing Whistler. I would recommend the AC30 if you plan to focus on the front side groomers. However if you are looking to do more off piste/powder, there are some better selections. Another point on the AC30, they are a very stiff set of skis for a begginer/intermediate. As such they can be a little harsh, but you can definitely grow into them.
Now for more west coast type conditions, I like the Blizzard Magnum 8.3, Watea 84/94, Head IM88, as well as the AC50. All of these are wider under foot (> 80 mm) and will give better floation in powder. As far as length, I would definitely recommend at least a 170 cm. If you choose a mid fat/fat ski for off piste, I would consider even going a little longer.
So try to determine the type of skiing you will be doing, and then you can select a ski that will make your ride rocking....
