Cecilio,
Interesting, but also the source of brain numbness. I couldn't keep up with the whole thing the first go'round having been real busy (thankfully) at the time. The variables are so numerous that a true scientific study would be a trememdous undertaking; and to what end? Furthermore one's personal opinion and preferances would still be the bottom line.
I'm comfortable with not having concrete answers for all of these questions and the fact that others opinions might differ from my own. As a matter of fact I prefer that; I don't think I could take another one of those threads without a LONG break. I'm glad the thread was of interest and of value to you. If anyone cares to take it up again I'll be inspecting my eyelids for holes until it's done. I'm all for the mystery in this case.
Brian Baylis La Mesa, CA Slept through it successfully once, I'll do it again if I have to. Nothing personal, just have limits on what and how long I can flog a dead horse.
