It's hard to believe that any water near you has no fish over 9" regardless the species. There's
got to be many small lakes you can fish for crappie and everything else that bites light jigs with various bodies. JMHO but you should consider using
much lighter jig heads and lures
less than 2" long. Thin diameter lines such as 8#test/4# diameter braid can make all the difference how the lure moves with rod tip twitches/ pauses. Even a 4# test fluorocarbon leader can do the trick using 1/32, 1/24 or 1/16 oz ball head jigs.
Change waters, slow the retrieve and cast all over the place. 1/8 oz makes the above technique
fish-uncatchable - especially when fish slow way down due to lowering water temperatures in fall. You'd even have a better chance using a float and light jig/small bait (hair or plastic). Fishing from a boat ups your chances 1000 %.
