I’m a regular long-line troller but gave leadcore a go this past fall and had some success with it on the St. Croix. I am usually a guy who tries to buy versatile gear that can be used for various situations and tactics, but after getting that lead spooled up I can say that it’s worth the extra money to have reels dedicated to lead and nothing else. I’m sure it’ll get easier with time, but it’s a challenge to get the leadcore tied properly to the backing and then the swivel on the business end. I like fishing a lot more than I like struggling to tie the Willis knot all day long.
Rods — you can spend a lot on trolling rods but it’s not necessary in my opinion. As long as the rod tip allows you to read the action of the lure you should be good to go. The Shimano TRD series comes in a variety of lengths and can be had for about $30. A lot of guys use Cabela’s Depthmaster rods are about the same price. You can also get those in combo form and save a bit.
Reels — A lot of guys seem to prefer a line counter, but I’m happy to just count the colors of lead going out. You want a traditional round baitcaster with enough spool capacity to fit your desired amount of lead. I like to have a reel with a clicker. I turn the clicker on set the reel to free-spool for minimum resistance. When line comes off your reel you’ll hear it.
