Ray, I usually have my mind made up on the size jigs I wanna fish when I'm in the backyard. That's not to say I wont change a few out on the lake or sometimes I'll change all of 'em out. I usually fishing early mornings and alot of times I'll see fish hitting bait on the top. That's when I want light jigs even though I might see fish on the graph 13' down. IMO I think the fish hitting the top are the aggressive ones. Sometimes they are...and sometimes they arent. I ALWAYS watch my graph though. I'm a firm believer the fish look up so as long as the jigs are running above the fish I feel I'm good. I don't know how much a crappie feels vibrations from their lateral lines but I have seen stripers on the graph come up 45 feet to take a bait. I don't thnk the jigs have to be in a crappie's face to get him to bite as long as theyre above them and youre in aggressive feeding fish. And if I'm marking fish and they aint bitinge then I don't stick around...I move somewhere else to fish and come back later.
