I wouldn't argue with someone who knows as much as you, but I would ask a lot of questions so I would be sure to understand it. That's the hard part, not being as smart, I need to fully understand. Don't use ME as an excuse not to do it. There are lots of people out there who would benefit by the looks of the forum traffic over the years. Scan and forward. No hurry since it will be a few years before I am ready to tackle my 216 project.
