Hi Cecil, I would highly advise everyone to do a "search"under Bill Cody. BC always has some great information and some real food for thought.It is interesting to look at all of Bill's posts on such a wide scale of aquatic topics.The many hours of reading past posts by everyone are such a wealth of knowledge. I also recommend everyone that uses or views this forum to be a subscriber to POND BOSS,its a great little investment.Take care, Ted
