I've been working up near Virago Sound (northern side) for 4 summers now, the issue is not what you can catch, it's what you might catch, I can tell you it'd definately be fun to hook into a decent sized spring, the trouble would be landing it. My wierdest unestpected catch was a coho line I put over the side of the boat I work on, I saw the hit, set it, and 15 minutes later, we had a harpooned 42 lb halibut on the deck.
I'll second the use of buzz bombs, there are lots of flounder and sole to be had, as well as a lot of lingcod, green ling, and you'll probably dredge up the odd coho, or even a small (or big...) halibut.
Nothing wrong with dragging a bucktail too if you're up to it.
I can't really speak too much to specific locations, but there's almost always fish to be had up north, so give it a shot, and good luck. Just be safe, wind and currents can be sketchy. A VHF is not a bad idea, or a GPS, but obviously wear a PFD.
