Spinnerbaits are reaction baits, use a nice steady retrieve around submerged cover, edges of logs.
I only have 2 colors, white and chartreuse, always use trailers, prefer willow blade in back, colorado up front.
If I do throw a spinnerbait in open water, it's horizontal to bank or shallow water, like coves.
If water is murky, I throw chartreuse with a black trailer.
