IMO paddle tails (sassy shad) and curl tails are faster/ steady retrieve lures. If you want to keep lures in the strike zone longer to provoke less active fish, I would go with a stinger (straight thin tail), Crappie Magnet grub or ribbon tail rigged on a 1/32 or 1/24 oz jig. The lures shown below are examples of tails that
quiver with the least action imparted.
The two on the left: swimbait tail designs; the other are variations of quiver- tails:
I bet my boat that you never considered this design:
take the curl tail off a curl tail grub and rig only the body. It catches panfish as well as any other lure with its
back & forth waddle &
quivering body. Also rig it on a light jig head.
