Once while fishing in a bass tournament, I got in a hurry to retie a Texas rigged plastic worm. I inadvertently put the sinker on backward. I decided to try it anyway and the reversed sinker technique has since put a lot fish in my boat. With the sinker facing the wrong way I found I could cast over a fallen tree branch and ease the bait up to the limb. When the cup of the sinker hits the limb, it stops the forward progress of the bait, instead of simply sliding over and falling lifelessly to the bottom. With the sinker nudged tight against the limb, the worm rises upward making for an easy target for the bass. With subtle pulls and releases, I have found I can work a worm forever in one spot. This is a great technique for cold front bass or lure weary bass. With that bait staring them right in the eye for long periods, the bass simply have to strike.
Another great use for the reversed sinker rig is to drag a plastic crawfish along the bottom. If its a hard bottom, the sinker cup rim will dig into the rock or gravel and make a lot of noise, again, the sinker cup automatically kicks the plastic bait straight up putting it in full view of any fish. When fished over mud flats or silted bottoms, the sinker stirs up a lot of debris and looks like a live crawfish feeding. Remember, drag the bait, don't hop it. There are many more uses you will discover by reversing the sinker, give it a try and let the Prostaff Team at Bassin' USA how you do.
