Colorado blades produce maximum vibration in muddy water. Their wide, rounded profile resists current and thumps hard with every rotation — that thump is what the bass tracks. Willow blades are built for flash in clear water; in mud, they nearly disappear.
Setup: Colorado single blade. Chartreuse or white skirt. Slow roll it just above bottom structure. Let the thump do the work — don't speed up to force reaction strikes.
