You mentioned a lake... so this might or might not be relevant.
If you've got decent current in a stream, a UL rig can zing a near weightless popper fly out into the current, where you can let it drift (maybe not as naturally as the fly-fishing crowd likes, but naturally enough) down a ways, and then retrieve. A "casting bubble" will get you more distance, but it always seemed to me to just complicate what can be simple.
Same goes for a 1-2 inch worm, basically a curly tail without the tail (or a micro-ned, if you want to think of it that way). The UL usually has enough snap to cast really light lures/bait like that, even without a jig head. If you want depth, a crappie jig head is in my experience more than enough.
As others have said, sometimes light and tiny is what the bass want.
