As good as spinnerfishing can be with a float, proper hardware fishing should be done without a float.
Master hardware tossers do not use floats as it definately limits the presentations you can perform.
Spinners can be used in may ways, but as with spoons, the down and across presentations are the key to mastering this approach.
I know of skilled hardware anglers who catch handfuls of steelies on the Vedder almost every trip in Febuary and march, almost all swing spoons using low profile reels and rods specifically designed for this purpose. The key to their success is the fact that the fish there are seldom presented with proper hardware techniques as few anglers have mastered this technique properly.
If you see an angler having multi hook ups using hardware, stop and watch them, much can be learned from an hour of watching these experts fish. Spoon fishing for steelies takes years to master and can be one of the most productive ways to catch steelies BAR NONE.
Check out "Spoon fishing for Steelhead" by Bill Herzog or "Spinner fishing for Steelhead " by Jed Davis, both these reads are sure to get you on the path to more success catching steelhead.
If you see me swinging spoons on the Vedder, I would suggest not watching for an hour ;D, I'm also still in the learning curve of this technique and may teach you more about losing spoons than catching with them.
