Thanks for the info, Sooner is one of the lakes I wanted to try soon. Always used to catch croaker on shrimp over shell beds, so it makes sense that the drum would like the zebra mussels. Not sure how edible a 10lb one would be, but the 12-16 inch croakers were always good, maybe try one in that size range if you ever get curious. Will have to look up recipes for black drum if I get one of the big ones, think maybe grilled with garlic butter or smoked would be a nice option.
