I have a 7 weight which I cast for at least 6 hours a day on a week long camping trip on the lower Skeena. I caught a ton of fish including a mid 20 lb. steelhead and it performed great! I used a 480 airflo Skagit Switch head, but a 420 works well too.
They are a bit beefier than other rods which is reassuring but are still pretty light.
