has anybody ever use this setup, did a search on you tube for roboworms and came across this setup.

I don't know about all that man!!!!

sorry this is the one with the roboworm, awesome action

I've tried it  a couple of times. I saw it on YouTube and that's what peaked my interest too. Haven't caught anything "multi-rigging" but I haven't tried very long at a time or with a variety of lures. Looks like Trick Worms, Lizards, Beavers, and a lot of other plastics would work this way. But it also looks to be pretty much a vertical presentation technique. May work in the shallows on rocks as long as the casts were not long. Good alternative to a shaky head rig.
