beach,
Here is a link to a site that is selling some j-plugs. http://www.google.com/products?sourceid ... 1&ct=title
Run them off of plainner boards, riggers, copper, dipsies or flat lined out the back of the boat. Troll them from 2.2 - 3.2 mph. They will dive some so don't put them too deep. This time of the year, j-plugs can out produce anything else in the water.
