If you need to go really deep, (and this takes more experience) let out more line and maintain your speed to get down to the depth where the fish are holding. Or you can double up on the jigs (2 1/16 jigs spaced about 12-18" apart). Don't be afraid to try something "out of the box". Sometimes I'll have close to 50 yds of line out when the fish are deep. Takes a long long time to reel 'em in but sometimes the big 'uns are deep.
GO BIG ORANGE !
I meant to behave, but there were just way too many other options available at the time.
