+1 on Megadestroyer after a year. Didn't like it that much fresh but brought a bottle home 2 yrs ago and it was awesome aged a year. Howe Sound is pretty much the only BC beer that makes it down here (Kokanee does not count as beer) and managed to find a couple megadestroyers a few months ago.
At 6 months my 1 bottle of Megadestoyer was better than fresh. I'm going to leave the other bottle for at least another 6 months.
From Howesound I find the Pothole Filler is a better stout. Problem is, it is really tough to come by.
