Should work. As the_chemist says, folks in BC swear by the Colorado blade under a float. Seems to me a Dick Nite, being so light, might be even better at "fluttering" naturally in the current. The Colorado blades would have the advantage of sinking better, but you could use an in-line sinker, tied to a 2-3 foot leader, to get you down in the zone more quickly.

Let us know how it works!
