Osmosis and I both have 5 wts. or 5/6 wts. but this year, I couldn't tell you how many 8-14 pound Coho were whacked with his fly stick. and my old school 5/6 has landed a few legit 15 lb. Skeena Steelhead, and about 4 dozen Russian river fish of all species, no chinook, but you know how that would go with a 5 wt. Even has a 24 pound Dog on its record...The hardest pound for pound fighter in the Salmon world...Purrty too when they streak out. Steelhead can be taken on stuff as light s 4wt, but go with a 5, or 5/6. You will really enjoy having 3 lb. brat stock Steel sink your rod a fair amount... The 8's, and 9's can grapple 50 lb. chinook easily, so go as light as you feel comfortable with. And when yo buy line, go one size larger than you are rated for. a 5 should get 6 wt. line, and so on. It will make casting a lot esaier in the beginning.
