That’s clever. I like that braided line going the length of the worm, it shouldn’t affect the subtle wobble of the worm. The Strike King and Yamamoto Senko have a nice action but the fish tear them up so easily.
I use the MJ Rig on a Big Bite Senko type worm. I fish it quite a bit since I first saw it on the Timmy Horton show. The MJ Rig spinner set up is available for $5.99 a 5 pack:
