Smallie,
I am sure we are looking for a rubber skirt material. But, from all the articles and info I have heard so far, I believe the material to be a heavier, wider slit living rubber.
I did check www.livingrubber.com and they only offer 2 colors in a rubber material described as "heavy". Unfortunately, neither color is appealing to me or I might give it a try.
The Buckeye Mop Jig looks different than the hand tied, home marketed jigs sold over in the Carolinas (or at least the skirt does). I have some Buckeye jigs and I have fished them, but they don't seem to have the "flairing" action the original jigs have.
Maybe there is another supplier that might have a "heavy living rubber" in more preferable colors that might be tried.
Smallie, thanks for your interest and help. Maybe together we might figure this puzzle out!!!
Mike
