Kincaid has some really large redears in it but you got to know how to fish for them. What you do is motor around some of the islands and land and find the points with the sand around them. A lot of the points that go out in the water will be sandy in Kincaid and what you do is sneak up to the point but do NOT get too close as you will spook the redears very easily. I use an ultralite rod and reel with a small splitshot and a live worm. I try to stay at least 10 feet away from where I'm fishing and more if can cast that far.
Don't use corks as I think they might scare the redears too and I toss out the worm and let it sink to the bottom and slowly reel it in. Once you find the big fellas they will be bunched up and you might pull 15-20 big keepers out of the same spot.
You shouldn't have trouble locating the sandy points but if you do, then find a section of the bank that is sandy with some stumps right out from it and that is where they like to concentrate too. The stumps need to be within 10 feet or so of the bank and you will find them about halfway between the stumps and the bank sometimes even in 8 feet of water but again use the single splitshot and a worm on the bottom.
Kincaid has some big fish in it but you gotta find them and it's a big lake so it takes multiple trips to learn where to go. If you fish up next to the bank in 2-3 feet of water you will catch tons of small bream all day long and this quickly turns some people off to the lake and they think there is no big fish there.
If you want to try another local lake, try Indian Creek as I never see anyone here posting reports on the lake. They have a great boat ramp but you have to pay I think it's $4 to get in to use it. Lots of lilly pads all over the lake and the big bluegill love those lilly pads. Fish the edges of them and keep moving around the bank until you find the pockets of big ones. Crickets and worms will work well for the gills and my favorite is just a plain hook with a very small cork and no lead weight. The cork gives me just enough weight to toss it up next to the lilly pads and then without weight the cricket slowly begins to sink under the water. The big gills go crazy over that slow falling cricket and hit it very hard.
