The JJ3 is a version of the the JJ2 but built to run deeper reaching 10ft during a cast. It has a larger lip and is a little heavier. Just like the JJ2 this will run very well in current and has produced some 30-40lb stripers using a high speed retrieve. It measures 11-1/2"s from the tip of the lip to the end of the flag and weighs about 4 ounces. Its a great trolling plug also!
