Assuming your casting????

Most ppm use different poles for perch and walleye. Perch you normally want a very light pole, walleye a little stiffer.

Perch you can get away with some pretty thin line or braid if your prefer. Never tried to cast braid, but on my perch I have 6 pound mono, of my casting pole I use 17lb floro, on my trolling rods I use 30lb braid.

Male sure if using lighter line to keep the drag set soft. The fish will take some line but your not putting all the force on the lighter line, or pulling on the fish hard.

When I get 's big on hooked up and not trolling one of the first things I do is loosen the drag
