This one's the result of mixing our Bleeding Shart with Rootbeer Shart lures giving it an extra UV reflective kick, you can see the two lures compared in the first couple pictures(UV RB is the top one in both) This one works in all weather conditions and water clarities. Capt. Dan Guerra has been doing absolute work with his clients field testing this lure over recent months and now through extreme demand, it's finally available!
