I agree with what was said above about depending on the jig. Heavy cover jigs have a thick weedguard and heavy wire hook so you need a at least a heavy action rod and the longer the better to get through the guard and drive the thick hook in. A good hookset for this kind of jig is more about about how much line you can move through the water. Same principal for long casts, which is typical if your fishing open water or really clear water, the more line you can move the better. I use a 7' heavy and a 7'6" heavy for these apps. Finesse jigs have a lighter weedguard and usually a medium wire hook. I use a 7' MH fast for this.
