I like to have backing stronger than the lead. The lead can "belly down" and catch in weeds and rocks causing strain on the backing if it's out, that's why I like to have a full ten colors on my main lead lines, as the weather warms up I will shorten my leader lines from 100' to 50' or shorter. Each color is 30 feet long, six colors and the leaders is about 240' or the other side of the lake... behind the boat. The main idea of using lead is to get the lure down to the fish, the mono leader will "float" up from the lead and visibility is less the deeper you go, so a shorter leader is okay. This "belly down" is what helps create action as you weave forward and currents move the line up and down. It is the main reason the planer boards work so well. I set up special in-line lead combos for using off the planer boards, again with a heavier backing, two or three colors of lead followed by a long leader, swivel, light floro carbon tied direct to the lure. You can use the same set up (all lead) either way but with the planer board lines out to the side, you can see the lead can hang down into the water at times and make you jump when the rod or line hops. Best of luck and tight lines!
