Hey bud, I've always just rigged them with a jig head.
I use them in slow estuary type water only. A tube head allows for a more horizontal minnow-like presentation under the float.
Also, while you will sometimes catch fish on them dead drifting, either a small ripple on the water or occasional twitches of the float help immensly.
Pencil style floats work better for this than round or oblong shaped floats.
If you attempt to twitch a roundish shaped float you'll invariably end up pulling it off whatever seam your drifting.
A pencil style float will "waggle" back and forth. You'll still give the jig action with a twitch, but won't pull it off course.
Cheers
