Hi ENgineer , welcome to the board. You could plug at the wall later in the season. Now you want small jigs. The standard jig is a 1/2 OZ upperman (flat head type) jig. They love teasers and plastic shad bodies and small fin s fish and curltails. All small stuff about 2 to 4 inches long. If you just want to plug , wait a month. then you might have some luck.
Go here to read about fishing the wall and about jig fishing techniques for the early spring.
