Wow, thanks to everyone for all your input. I am finally beginning to understand the hows and whys of different settings and how they integrate and impact each other. Also, I'm sure everyone here already knows this, but the folks at Axiom are excellent. I just hung up with John and he really helped me understand the whys of different settings. I'm one of those people who wants to understand the "behind the scenes" and what is happening when mains are set to small or large, etc... All of your input and John's explanation have been very helpful. So now I'll go do what everyone has been telling me to do from the start because now I understand why I'm doing it!!!!!
