I'd do an 8 weight in this case. You might be a little light for Salmon, but otherwise your in good shape. It will do saltwater well too.
I can't tell you much about either of the rods you mentioned, but I would lean toward faster action. Someone else on these forums recently put it well. Feeling the rod load doesn't have to mean that you are putting a deep bend into it. Typically, fast rods have a bit softer tips, and they can communicate the cast very well.
