I would have loved to use this an excuse to pick up the L85 for the British, or just go with US since I have some of the basic stuff already. But if you're going to go to an international event, why not represent Canada? I think it'd be awesome to have a quality Canadian team, that are willing to do what the other countries can't. Vimmy Ridge, and so on.
It'll also be a good learning experience (hopefully) for myself, as I don't know much about Canada's military history as far as their outfitting goes.
