It wouldn't hurt to try unbrella rigs. My uncle used them on Lake Cumberland with good results. One of my friends brought a setup from his saltwater box to wateree and tie on a bunch of mix lures on it and lost every single one of them. wasn't me ok. Best to use the same lure multiple times not a Rapala plug on one corner and 3 spinnerbaits on the other. I knew the owner of Cedar Creek tackle used mini umbrellas for crappies and the guys on Clarks Hill are big on them for crappie too.
