The rod I throw my top waters on depends on the size of the bait. Smaller stuff (spooks, poppers, small whopper plopper) gets thrown on a medium fast. Bigger stuff (wake baits, buzz baits) gets thrown on a medium heavy fast. And the really big stuff (got some big inline buzz baits and wake baits) gets thrown on a heavy. I throw my frogs on a medium heavy, but I run straight braid on that one. Hope that helps! Basically, the size of the bait dictates the rod it gets thrown on.
