The spinnerbait is my favorite bait, you can fish it a lot of different ways. That said, you may just be fishing it in a manner in which the fish aren't reacting to it or the fish aren't active enough to chase. Before putting the bait down for something else there are 5 things you can do to find out if the fish are active enough for a spinnerbait. The first is to change the retrieve speed, either slow it down and slow roll it on or near the bottom, or speed it up to fish in the middle of the water column, or burn it just under the surface, if fish are active one of those retrieves will draw a strike. The second thing is to change color , I won a small tournament using a spinnerbait that was different that what everyone else was using. The third thing is to change the size of the bait, going up or down in size can make a big difference as well as sometimes if there is an abundant type of forage the fish can get locked on to a certain size, it may be small Alewife minnows or bigger bluegill but you need to keep that in mind. The fourth thing is using different blade configurations, if a single willow isn't working then maybe a Colorado or Indiana may be better or a double willow. The fifth thing would be to use a trailer, I don't use trailers very often on spinnerbaits but there are times when it really helps. Those are just some general things you can try to change with the lure itself but remember, sometimes the conditions just don't make for good spinnerbait fishing. For me the optimum time for spinnerbaits are when you have a little overcast with a light wind, enough that it puts a chop on the water surface. Wind really does seem to make for good spinnerbait fishing even in bright sun but there are a lot of variables that can be good or bad for that lure. Things like water temperature, water clarity, light levels (sunny-overcast, early-late in day), and forage all play roles in what lures work and which don't, so what you do is try changing the bait up along with using multiple retrieves and if it all fails try using a slower presentation because there will be times the fish will not chase a moving bait and a slower presentation is needed.
