Another advantage of floats is the ease of placing your lure smack-dab in the middle of a steelhead’s lie. Suppose you want to fish a long seam where slow and fast currents meet. No problem. Simply cast your float past the lie and retrieve line until your float is just at the edge of the seam. Now free spool line while the float bounces along in perfect position to pass over the fish.
The float really shows its stuff when working pocket water behind boulders. You can flip the float past your target, then reel in until the float and its payload are swirling merrily in the back eddy. You can let your lure swirl in the back eddy as long as you like. Try that with conventional gear and odds are your tackle will look as though its been in a blender.
