This was a good write up. It gave some nice details and allows you to draw your own conclusions.
OP, I do have to say that it cracks me up when people do a nice write up but include the caveat "he is an engineer". Why throw that in the mix? OK, the guy took a test and passed. Does that make him more qualified than the guy tinkering in his basement? Nope. Trust me, I manage a group of engineers. I correct equasions, formulas, grammar and everything else. I don't have any degrees. Just a regular high school grad. Again, great write up but really, the caveat is not impressive...
