I have three 1980's era 4/0 reels (a Penn 113H, and 2 Daiwa Sealine 400H) which would work just fine. Was thinking about putting new line on one of them and using with a Fenwick Pacific Stick 7 foot 670C. However, I've been going out on a 6-pack from La Push (Allways Fishing) and have been using the boats gear. Not sure of actual brand name of gear but it was a level wind, no larger than 4/0 (maybe smaller) and was loaded with 80 lb. synthetic (braided?) line. It was a very good combination. Even at 600 feet depth, you could easily feel the bottom with that line and a weight/jig of approx. 2 lbs. This combo brought up an 87 lb. halibut last June and a limit of lingcod. From 600 feet down, it can be a long slow process bringing up a large halibut but with the above combo of rod, reel and line it is easily accomplished. Don't forget the Smelly Jelly.
