With bouncers I don’t use a line counter. I just drop the rig in while moving, find the bottom and give it a few reels before setting it in a rod holder or holding it in my hand.
If I am pulling cranks in less than 13-14′, it is always braid with about a 6-8′ mono leader attached with a very small ball bearing swivel. Braid is extremely sensitive and with just a little experience it is simple to tell if baits are fouled in any way. If I am pulling cranks in anything over 13-14′, I run leadcore as lead lets me put smaller baits (#5 and 6 raps) deeper consistently. Leadcore also tracks the path of the boat better with a little bow versus “cutting the corner” like braid does as you maneuver the boat. The sacrifice with lead is losing some sensitivity and just the general added work of bringing a fish in while trolling the opposite direction on lead line.
