Mix it up...I run storm tandems that have a 5' and 10' leaders then I run parachutes 6 and 12' then run a WWB with a spoon 6 and 15'. The main thing is that there is at least 2-3oz difference between the two baits. Other than that mix it up a bit. On Saturday we were getting hit a lot on a 6oz parachute in tandem with a little 6'' storm shad 50' off the board. Those lines are 6' and 12'.
