My biggest bass ever caught on spinning gear was 24". It was in a small pond in the middle of nowhere in Northeast Pennsylvania.. I caught it near a stick-up after seeing a swirl in the water, on a 4" junebug Yum dinger, using 8 lb test Yo Zuri Hybrid line, an Okuma 7' Reflexions rod, and a cheap Daiwa 8 ball bearing spinning reel.
