Was there any advantage to this or just something different. I guess it might fall a lil flatter with the rear weighting.

 

I think that is an old "weed sneak" jig head.  You put the skirt on from the front, rather than bending it around the hook & up.  Back in the day, they came with a little plastic cone, where you threaded your line through the cone prior to tying your knot to the hook.  Then you slid the cone down over the knot.  This protected the knot somewhat and offered a slicker profile for bringing the jig through weeds.

 

As I recall, it never really caught on and after a year or so I never saw it marketed again.  (We're talking mid 80's to late 80's here, I think).

 

The one advantage to the jig was that it was easy to change skirt colors.

Oh yeah. I remember the one with the plastig cap that snapped on. I'm thinking those were Blue Fox maybe?
