The KVD Pro Model Tube is salt-impregnated, and is great when finesse is the name of the game. This 3.5″ length is a perfect all-around size. Tour Grade Tube Jig Heads can be slid inside the tube with the line tie poked through. This bait works well on light line and spinning rod applications, but is equally effective Texas rigged and flipped. This is the finesse bait that helped make Kevin VanDam the 2001 Bassmaster Classic winner!
