This is good info....I just wanted to reply so it can come back up to the top. I was kind of floppin' around with stuff, not really knowing what meant what, trying to get all the little pieces I'd get from the 'old guys' (yes, yet another movie reference....men in black 2). But this put it all together for me and I feel much more confidence with my AG setup now, knowing I have a stable platform to start with.
Thanks, Pat, and Curly55 for putting the link in a post! Big help!!
