I like medium and medium lite actions best. For throwing spinners, cranks, jerkbaits, and topwaters, i like a slow action rod with a lot of flex. Seems to help keep fish hooked better.
For bait and jigs, I like stiffer rods with a fast tip and far less flex. I feel the hits better and set hooks better.
I have 13 different open water setups and several ice setups. No one rod and reel combo works for all species. But medium light and medium is best for predators like trout, bass, walleye, and pike. Catfish call for heavier gear.
