I usually start out with some type of reaction lure...spinnerbait, cranks - lipless and billed, etc in hopes that the fish are active and roaming as you menioned. In any case, I find that the smaller ones are more active than the larger ones in any case. If you think that they are relating to cover then go for the weedlines. Right now, up here anyway, they are relating to the second weedline, which from the bank is a long cast. Now you have to figure if they are on the edge or "in the weeds". When I decide that they are in cover, for me anyway, it's a jig, tube bait or weightless soft plastic stick bait, i.e. senko type bait. My tactic is a tube and or jig first and then soft plastic stick bait.
With that said, they throw you a deuce and you can catch one in 1-2 feet of water like I did yesterday:
The spot:
Got her right in the middle of the horeshoe shape of the lilly pads. I never thought she would be there on this day.
So in a nut shell, small bodies of water allow you explore all possible scenarios in a short amount of time. Use all your techniques at your disposal and just enjoy your time out there. These little green things will surprise you. Just take mental or written notes of those spots you caught fish on, quickly go over the less productive spots and start the process all over again as the season changes. The less productive spots may be the more productive spots later in the year as I'm finding year in and year out.
I tend to throw out all this info after my fishing season ends. The small ponds I fish at tend to change from one year to the next, for whatever reason.
Good luck and have fun.
