I fish the Linton area myself...here is the funniest way that I have found to catch crappie...use a 6 foot medium action spinning rod with choice of spinning reel...spool it with 6 or 8 lbs mono...then I use 1/16 ounce weedless jigs with a chartuese/sparkle curly tail, or white curly tail, or orange/chartuese solid body umbrella tube 1 1/2 inch long.
Now that you have your equipment ...its time to start fishing...idle around the points..even the fish ID bouys are good...main thing is find underwater brush on your graph in anywhere form 10 to 18 foot deep...when you pass over it throw a marker bouy out and stop the boat and fish it...stay back off the marked brush and throw past it letting your jig sink to different depths by counting it down...then reel very very very slowly....holding your rod in one place and still....normally when you pull free from a piece of brush you will feel a thump....Set the HOOK!

Remember don't pull the jig through the brush using your rod because it will be hard to detect the thump...just reel slow and set the hook when you feel a tick or thump or sometimes if the line goes slack in winter. Have fun and its is addictive.
