I'm new too in Vancouver. And I'm also from Europe (in France).
So for the size of your board, I advise you to stay on 149. Why? Because it will be more manageable for you. You will not need more unless you decide to go in the snow.
Once, not that I do not like Rossignol, but I think there are more versatile boards for you, and best suited to your program, and especially to your evolution.
You've found a shop in Vancouver? Where it without indiscretion?
Is what you bought your boots? (Most important to me, compared to buying a board and bindings).
If you want, I can help in the selection of boards, especially since I work in the snowboard industry.
Contacting me message, and why not go riding or have a drink one day
