Missouri Smallmouth Alliance is membership based and is mostly for the St Louis area. Dan Kreher and Matt Wier run that one.
Ozarks smallmouth alliance is based out of the Springfield area.
There aren't enough officers available to enforce the rules as it is. I've been on lakes in southern Illinois that allow larger motors to run at idle/no wake (very subjective and no one follows those rules anyways). IMO, the 10 hp restrictions keeps the big boats off the water making for a much more peaceful experience. If it's not broken, don't fix it.
Some of the lips will work better than others, and I use a good bit of cement to keep them from spinning on the shank. I'd recommend using them on articulated flies. I've caught a few fish on them but I don't typically throw them much any more. The first time I made one, I took it to a local area to try out. I was tossing a short cast to see how it would act and this muskie crushed it with about 10 feet of line out!
This is a good place to get jigs. You can custom order with whatever size hook/lead you want. It's out of springfield IL as well, so rather local. Most of my hair jigs for smallies are olive/dark olive or baitfish colors. Can't ever go wrong with white or black as well. Best to keep them sparse most of the time ;).

I am sure they will suck that thing down. The grass carp around here select for certain kinds of leaves. I see them pulling branches of walnut trees when the river is flooded, and any downed walnut is stripped of it's leaves in hours while the maples go untouched. They do love the maple seeds (helicopters) though, cottonwood fluff, and other leaves. I'm going to have to figure how to tie a leaf imitation.
