I have found personally, that the trailer makes a big difference on a chatterbait and so does the weight and speed of retrieve. I like to wake them under the surface kind of on the slow side in stained water and a 1/2 oz is a good size, or 3/8 and I have found if I use a boot tail trailer it pushed too much water at times and fish will miss it more than they get hooked as it gives the bait a wide swing...I like to use a simple 4-5" curly tail grub and if I can use a trailer hook I will if grass is not an issue, and just like a spinnerbait, I often do best when the bait is at the level where I can barely see it....Some guys bend the blades to get more thump, or add a split ring etc..but for the ZMan baits, I like them with the skirt trimmed short, I like to color the blade with a black sharpie or will use gold in stained water, and often I like to wake it and the bigger the trailer the slower I retrieve it....
You can fish the chatterbait so many ways, it is more of a crankbait to me than a spinnerbait, I like to make it jump and deflect by giving it a few quick turns and pauses here and there, but like most lures, I seem to do better by changing speeds even if it is just a quick stutter or quick turn of the handle....My favorite way to fish them is like using a lipless crankbait in grass..I like to let it tick the tops and then let it bury a bit and rip it out, but some days it is too much and a Spinnerbait or Crankbait is better, or sometimes the small 1/8-1/4 versions are better as they all put of plenty of vibration.....
I throw bladed jigs on every trip and some days they will not touch it, some days they miss it but smack it hard and give away location so I follow up with a soft bait, but when they want it, they usually let you know....Don't give up on it, Experiment with trailers from grubs, twin tail grubs, bulky beavers or creatures, floating baits like the Z Man or Strike King Zulu Flukes, and taking of the skirt is popular but I personally like a trimmed skirt and more bulk so I can get more action going slow...I hope that helps, I feel like I learn new things about the chatterbait every time I use it, and the Trailer makes a huge difference, sometimes leave off a trailer or simply use a spinnerbait Cajun style trailer in chartreuse just to give it some color contrast.....
