Turning to Walleye...

If I were you I'd just ask the guys you are going to be fishing with about what tackle you will need. They will be more than happy to tell you (everybody likes to be the "expert"). I've always had the best luck by keeping it simple and as light as possible for the conditions.

I'd take both 1 oz and 2 oz BB, and a longer softer action rod if I planned to pull spinners. They like to come up and just hold on, and if the rod's too stiff they will drop the bait. There are a lot of options out there, but really one doesn't need to spend a lot of money for a good bb stick. I like the Berkley Air in an 8'6" medium action, and on the low end the Cabelas Whuppn sticks in a medium action work well but i haven't had much success keeping them together for an extended period.

You have a nice collection already. The lightest rod I'd take would be a ML. With you being used to musky rods even the ML is going to feel too flimsy.
