@ Skinny and Ivy
Gents,
we're all working off best guesses, info we hear, read etc.
Differing is not a bad thing. Its what forums are for. We all put our 2 cents in and teach others, and learn something ourselves.
Noone has the asnwers, so a good dialogue with guys genuinely contributing is not to be taken personally.
Personally I appreciate both your posts and hope you'll continue to help us young'ns out.
