I'm fishing for smallmouth in clear water so I've made these rigs with Gamakatsu 584 EWG hooks which I had been previously TX rigging with small creatures and 5" hula grubs.
Dressed with a Smallie Beaver, this innovative assemblage of hook, rings and weight received the seal of approval during yesterday's outing.
