spider rig them out the front and use the reelfoot setup to rig them. 3-way swivel @ top of your set-up..about 6-8 inches of line off 3rd swivel and attach first crankbait..drop about 2 feet of leader from 2nd swivel and about halfway down take a 1/2 oz egg sinker (w/ hole thru the sinker) and run your line thru the sinker 3-4 times. This will hold the sinker in place where you want it. Now attach your 2nd crank bait to the remaining line below the sinker. I use loop knots to tie to cranks..gives them much more action. When you drop the set-up into the water have your troling motor on and slowly lower it in watch your crankbaits running to make sure they are not snagged on the main line. Drop into the water and your cranking for crappies. You can use any crankbaits that somewhat imitate a minnow. Not to small but not too big either. I have had success using the cheap silver, minnow shaped renegade crankbaits you find @ wallyworld (walmart) in the fishing section (obviously). They will have them on bottom rack in a box for a $1 under the fishing lures. Sometimes they have them and sometimes they don't. BPS will also have deals on cranks from time to time. Get several when you find some you like. You will get broke off occasionally so don't buy 3-5 dollar cranks unless you just want to. You will catch other species once in awhile. Fun way to fish for crappie and can and will be successful.
