I've had plenty of luck catching Chain Pickeral in the fall on white spinners. I would make sure you really want them before you put them in. They are toothy preditors that eat anything. I put three 16"-18" CP in my 5 acre pond to help with the overpopulated bass, and within 2 years we pulled out 2 of them at 26". I left 1 in for the hell of it, but didn't want them spawning. They compete pretty well with LMB, but might outcompete Smallies.
