I have always rigged rubber out the top. Usually I use a weigted head and cut back the rubber a little to make it fit on the head so the rubber and lead match up and then a little dab of super glue to keep it on better. Fishing the ditch, the method GS shows would be a little light (for most applications) and I'm not an expert on boats and stuff....
IMO, rigging out the top is like fishing a live eel (through the mouth out the eye), fishing a bucktail, fishing an eel skin jig and most other methods other than plugs which would not swim if the hooks were out the back, actually it would probably swim but it would just flip to the "right way". Also, rigging out the bottom will tend to snag more in rocky places. My hookups with single hook jigs of all sorts out the top is pretty high in conjunction with Cortland Spectron. I like it on top
