I would bring medium to heavy baitcasting tackle and leave the light stuff at home. I rarely use line under 15# test on Guntersville ... unless I'm crappie fishing. My go to baits in March are a jig 'n pig, a rat'L trap, and a suspending jerk bait. Later in the month, when it is warmer, I fish a weightless Yum Dinger (Senko type bait). February and March are the best months to put a double digit bass in the boat. It is not unusual to weigh in a best five over 30 pounds that time of year. A 20 pound sack usually won't get you a check. Good Luck and catch some big 'uns!
