Tim, again your input regarding this film and my questions are appreciated.
Donald, I respect your technical posts here and I thank you. I realize you are a Phill Davis disciple and I myself have been trying to absorb his book I have recently received, although the BTZS Light CD that came with the book does seem inviting.
Steve, I think it goes with out saying that the work and testing you have published on this forum has been appreciated and used by myself as well as many others. Steve thank you for your input.
