These Spinnerbaits (Colorado blade) have a loud vibration that helps bass key into the bait with their lateral lines and is very effective in muddy water. Also, these Spinnerbaits are perfect for fishing slow because the blade keeps spinning at a low rate of speed and will not tip over. White Ice is the classic "white" pattern that every company sells but with a twist of sparkles that brings more life and bites to this awesome bait.
