Yum Spine Craw Bait 3.75in Summer Gill. The 3.75-inch craw features angled appendages along the body that serve two purposes. First they displace more water. Secondly they slow the Spine Craws descent through the water column - which allows anglers to use a heavier weight when flipping for more accuracy. But the Spine Craw isnt just a flipping bait it works as a trailer and can be Texas or Carolina rigged.
