Match your plastics to the size of the baitfish you are seeing. If you are fishing for LMB or Whites, choose a simple color for the four outside swimmers, and a contrasting color on the middle. The weight of you heads/hooks will dictate what you throw it on. A steady retrieve is fine, but the occasional 'FLASH', or 'BURN' will sometimes trigger a strike. If you are looking for saltwater, buy a different Umbrella Rig designed for it.
Lately I like 3-4" ribbed swimmers like the Keitech; BPS Speed Swimmers; Kicker Fish Tail Slappers. I use these smaller ones on a 1/8 oz jig head. I have gone down to a light wire 1/16 just to make it a little more compact and easier to cast. A 4-5" on a 1/4 oz for the middle.
White, White Ice, Sexy Shad, or Threadfin Shad have been my colors of late.
