1. For a 9wt rod, is a floating, sinking or an interchangeable line better
suited for steelhead/salmon fishing in fast water?

If steelhead or salmon are taking in fast water, they
are usually on the bottom, i.e. you need a sinking or sink-tip
line (selected according to how fast it will sink the fly
and how deep the water is.)
