Small lures catch everything and especially many soft plastics rigged on light ballhead jigs. The casting distance may not be as far as when using a float, but the jig+plastic weight still casts out to 30-40'. Covering water is most important but making sure the slowest retrieve possible keeps the lure in the zone long enough to work those fish senses. The lures in the posts above are all capable of getting strikes due to their subtle actions that fish attack with gusto! The lure actions I refer to are many and ones you might want to make note of when choosing lures. Here are a few:

Waddle
A piece of a plastic worm attached to a 1/24 or 1/32 oz jig, when twitched with the rod tip has a waddle & dart action. This one was made by attaching a part of one lure to a small grub body:


Quiver tails quiver and flutter even on the slowest retrieves. These wacky rigged lures have tails that quiver like crazy when your rod tip imparts the action:



Many lures sold have those very thin tails certain to provoke strikes. As suggested in the previous post, a small bit of silicone skirt pull through the body has the same quiver.

The Crappie Magnet and Trout Magnet double tails are classic fish catchers. The action is unique and in a class of its own:


A curl tail flapping like a flag in the wind is felt by the lateral line and equates to a slap-in-the-face to a panfish:



Thin straight tails also have a nice subtle quiver:



The Joker tri-tail also has a unique quiver:


The point I'm trying to make is not that you should look for any of the specific lures above, but note the large number of lure actions in everyone's plus my post that catch fish all year round and most species of fish at that! Color is a personal choice based on fish caught. No one can say one color is superior to another whereas color brightness may enhance a lure's action visually thereby adding to the unnatural contrast underwater that fish respond to when using lures.
