AussieBGH:

The summation of both answers to the question provided by Ripp and Rolf is so good and so concise those two posts distill 50 years of discussion into just several paragraphs.

Now, the question: "Which one do you WANT?"

I picked the H&H version but those guys really nailed the issues down tight and I have nothing to add.

Please let us know what do DO pick....and why!
