Hmm...
I guess the definition of hardbaits would have to be clarified before I could answer in detail.
But, more than that, I guess I would have to consider the conditions at hand.
Windy days will probably find me chunking a spinnerbait, buzzbait or lipless crankbait (Rat-L-Trap or similar).
Days with little or no wind will probably have me throwing soft plastics, like the Salty-B-Bug, Stick Worm or similar.
So, to answer your question, Both! Hardbaits and softbaits.
