Like you slwndwn, I still have a couple of old Fenwick Rigger Sticks with the twist guides...great rods, but a little heavy for my taste too.
Over 20 years ago, I bought two Sage 10.5 ft GSH 3106LB rods. They're essentially west coast style centre pin rods. A little heavier than we typically use here in the Great Lakes. I have used them for exactly that with float reels on trips to the Skeena system, and one especially memorable trip to the Dean. However, the primary reason I got them was to use them as rigger rods here in Ontario. I have Islander Mooching reels on them. The fight with a single-action reel, and the ability to "palm" the reel when a King decides to head for the other side of the lake, makes Salmon fishing a blast. They really won't handle heavy set-ups that well....like Spin Doctors or Twinkie Rigs, and I certainly wouldn't run wire or Dipsy's on them...but for straight up spoons or body baits off the riggers they're perfect. A lot more fun than cranking on a Tekota.
Anyway, you may want to take a look at float rods...they certainly have that desirable slow action...and there's a number of models in the 11ft range. An old school 9 to 10 ft noodle rod would also probably be something to look at..
I will say, that if you're using the "baitrunner" function of your spinning reels to let out line when you drop the balls, it can become problematic. Line twist will become an issue. Just speaking from my own experience using a Shimano Thunnus that I own during some offshore salt water trips down south. It's better to just open the bail if you're letting out any considerable amount of line...but then again, it's the same problem when a fish makes a long run.
