Just pick up a Cabelas rod, reel and you shouldn't need a spool for sinking line. You will be fishing in 4 ft. to 12" of water. Use Tyger for a tooth leader and white bunny flies with red heads. A four piece 9 ft. will fit in a duffel type wheeled luggage bag (Costco). Worked great for us on three trips up there so far. You can even take back the rod after you get home if you didn't like it or just want your money back.
If ya don't find what you are looking for, let me know. I have a 8wt STH Caribbean with 2 spools. Both lined with backing and ready to go. One spool is WTF the other is sinking. The reel is heavy but work well. I bought them used for an Alaska trip a couple years back. It landed 500+ fish easily in 11 days. Everything from reds-huge Dolly Varden. The reel is left hand retrieve. And can't be changed unless it is sent to the dealership. And that isn't easy either. Don't ask how I know. LOL
