I know this is an old thread but wanted to add my $ .02 worth. If you ever need a question answered, please don't forget about the Cast Boolits chatroom. You can usually find a very knowledgable person in the chatroom who will answer your questions. I find that not only do I gain from reading as many posts as I can, I always have a place I can go (esp. if I'm impatient) to seek help and interact with "real time" individuals who can steer me straight. However, be advised that some of the "old timers" like to yank your chain but their knowledge is invaluable. BC
