In the spring, I often mix bass and crappie fishing. For crappie, we have St. Croix Premiere ultralight rods, and 1000 size Diawa and Shimano reels. We always use 4lb mono line, and usually fish small jigs below a bobber. I don't intentionally fish for bass with these rigs, but bass often strike the small jigs. The biggest bass Ive caught on these ultralight rigs was a 5lb fish. I've caught many smaller bass over the years. It's a hair raising fight. Rod bent like a pretzel, drag screaming, and trying to keep a good fish away from cover,( especially wood cover). I know there are folks who use ultralight tackle for all fishing, including bass. The bigger bass can be landed on this tackle, but you've got to play them carefully, and hope they don't get wrapped up in thick weeds or wood. What's the largest bass you've ever caught on ultralight gear?
