For me, two piece slow sink lipless swimbaits swim in a lazy S pattern. The longer the bait, the bigger the S. They will catch fish all year.
Three piece faster sink baits swim with the tail section flapping like a flag in the wind. Great for faster retrieves, in early spring next to steep walls, and anytime the water is 55 degrees and up. I also like them fished fast across submerged weeds. They move enough water to draw reaction strikes from fish in the grass.
Four piece slow sink baits swim in more snake like pattern, wiggling along. They are great at any speed, and in warmer (55 and up) water. I get a lot more followers who don't commit with a four piece. It gets their attention, but not as aggressively, so I usually have to trigger strikes by speeding up the bait, or having it do a 180 degree turn and pause, so it's looking back at the follower. But lots of times the bass just turn away, like they were just curious, but not interested in eating.
Try giving your baits a V cross section, with the back and shoulders thicker than the belly, like 1" at the top, and 5/8" at the bottom. That way, the back/top of the bait is naturally more buoyant, so your bait won't roll on a fast retrieve. And keep your ballast as low as possible, and in the front section(s), never in the tail. That way the bait will swim level, instead of tail down.
I don't know how to make a jointed bait that will hold up to a musky, but I've had some eaten by barracudas. Plan on doing repairs.
