Steelhead/king setup

Looking at getting a st Croix avid float rod. I can get a pretty good deal on a 11' Light. Line weight is 4-8lbs which would be more ideal for steelhead. Would that be too light for kings? I was thinking about putting some 10lb on the reel for my mainline which I know is little to much for the rod. Just looking for a little input. I was also thinking about just trying to get a med light since it's 6-10 line weight and I think that would be a little more versatile rod for steel and Kings....
