It really just depends on if you plan on swinging or nymphing?? If you will be mainly nymphing then a floating line will be what you will want. If you will be mainly swinging, then you will want a sink tip of some degree (grains) for different depth. And, like TD said that would be the way to go at some point, two spools. Since you are just starting I would suggest a floating line. Nymphing will be more productive for you to begin fly fishing for steelhead. You can always get a section of sink tip line, like a MOW tip, and attach it line to line through the loops, similar to a VersiTip, without buying the whole package.
