I have a rod/reel that my dad used to use for trolling on Lake Wallenpaupak, and a couple other lakes around there. Not sure what the rod is, but the reel is a Diawa 47LC. He has leadcore on it. I don't think they make that model any more, but there are updated versions. It's a nice line counter reel, and worked well for my dad when he was using it. That rod/reel is on ladder hooks in my garage, along with a bunch of surf fishing combos that I really need to use all that stuff again.
To avoid reeling your terminal tackle down onto the reel, which also has the chance to damage ceramic guides on your rod, thread on a bead that is bigger than your tip top guide, right before the swivel or snap on the end of the leadcore. Set the drag to slip when that bead hits the guide.
