In Oklahoma, we only have 2 types of water: Cold and Muddy, or Hot and Muddy.
You're not going to believe me, but I watched 2 guys catch fish using micro jigs (the kind I only see when guys are ice fishing on TV) two days ago when the water was muddy and 35*. I mean TINY. The smallest heads BPS has around here are 1/100th, so I bought them and tied up a couple. Tail only cleared the hook by about 1/8". My buddy went out the next day (yesterday) and I told him to try them. He did WAY better than I did on Saturday. No scent or vibration. I say all that to say this: somehow the fish can see even when we can't.
But if it makes you feel better, use something with vibration like Road Runners (that blade is not just for flash), or scent like Crappie Nibbles, or of course minnows. If you use minnows in cold water, choke your weight down close to the bait so it can't swim too far. Crappie won't chase as hard/far in the cold as they will the rest of the year.
And definitely slow down your presention of jigs. Pay more attention to depth, because if they're holding at 11ft, and you're at 9 or 13, there's no guarantee they'll see your lure. But if you can get it back down to the exact depth they're holding at, you can put it right on their nose. Muddy water will shrink the strike zone, but it won't shut their lips.
Jeremiah 16:16a "But now I will send for many fishermen," declares the Lord, "and they will catch them."
