Book a trip for October and go to Vancouver island.
Forget sockeye fishing, as it is almost a complete snag show (very few exceptions in clear water where they will bite bait).
Sport fishing... I'd say October. A huge number of coho start showing up all over the island at this point. The first 2 weeks of October would be prime because you can still get clean coho in rivers on the west side of the island, and peak run on the east side will just be starting. There will also be a huge number of coho off a number of beaches, along with the odd chinook. Steelhead fishing is also amazing at this point. Pinks wont be around as they are done in the beginning of September. Lots of cutthroat around as well feeding on salmon eggs, etc.
If you want to go for a huge meat harvest, then come to the island in September. Coho will be flooding rivers on the west coast of the island, and the limit on the stamp is 2/day per person. Chinook will also be running very strong on the island in a number of west coast rivers and off some beaches which allow retention. Add on to that some spectacular summer run steelhead fishing in a number of rivers (all catch and release). If you want to enjoy some amazing scenery, remote locations (probably won't see another person), and the potential for some amazing fishing, that would be my option.
As for gear. If you're going to the fraser for sockeye... a spinning rod will be all you need, and lets be honest, it is snagging and people only do it for meat... If you're sport fishing, my advice is stay away.
On the island, you can spin fish off the beaches and in most of the rivers. Coho love spinners and spoons. Off the beaches trebles are allowed (have to be barbless), in rivers, only single barbless is allowed. Actually, most times of year on the island all I do is spin fish now with spoons and spinners, it's highly effective for everything.
