Here is a link to probably one of the best sources of information on correct jigging technique and general information on jigging. You may have seen Mr. Benny mentioned it but never took the time to investigate. Can "Strongly" reccomend that you take the time to study this site. It will provide excellent guidance for both rookies and veterans alike.
My .37 cents worth for your consideration.
