I use Hal-Fly's or curly tails in the summer. You want to use 1/24 or smaller for a slow fall. In the summer the fish are aggressive and bite most anything. Look for docks with at least 6 to 8 feet of water or deeper. Look for your line to jump or move or go limp. In the summer you might even feel them hit if they are real aggressive. You will catch a lot more crappie if you learn to see your line move. If you use bright green line it is easier to see the line move or at least for my old eyes. Shooting docks is like bass fishing, every dock is a new adventure, just like each bass hole might be the one to catch a bunch. I have caught 88 fish off of one dock. It is a lot of fun. Good luck.
