You guys have had luck with the heavy jigs? I have not, seems they fall too fast to stay in strike zone but I can give it another whirl.
heaviest ive thrown is 1 oz but in order to get a slower rate of fall you need somewhat of a bulky plastic. what i mean by bulky is something wide and flat like a havoc craw fatty or something along those lines, the weight will still pull it down relatively quick but the added water resistence of the bait will slow it down a bit almost like a parachute. as for keeping it in strike zone thats the reason you want to lift your rod tip slowly a few times after your jig hits bottom, you kind of jig it a few times back into the strike zone then if no bite retrieve and pitch to another spot and repeat. what you want is to kind of have your jig hit things on the way back up , like if you can bump a few lilly stalks or whatever stems that are attached to the veg you are fishing and almost try to get the jig stuck on the way up. it sounds crazy why would you want it to get stuck? well you dont want it snagged but stuck so that it hits a stem on the way up and then falls again when you release line pressure, this in my experiance tends to trigger strikes. ive never gone punching heavy dense vegetation but when i flip lilly pads or marsh grass ,ect this getting stuck then releasing motion tends to get me bit , almost like my jig was trying to escape back to the surface but hit a wall and had to go back down to find another way up, the bass sees this and thinks hmmm this thing looks like its in trouble so ill go in for a bite lol
