Wondering if any of the jigging experts out there could provide some basics of jigging for bottom fish. I have tried jigging off and on for a quite a while and have never had much success. I've tried buck tails, diamond jigs, flat fall and slow pitch jigs. I have the right equipment and jigs recommended by others. I see them catching fish after fish but all I do is wear out my back and arms. Any basic advice, do's and don'ts, etc. would be appreciated.
