Mike did one or two of my PCs in the -400, I never had a line flight with him. The PCs were fair with good grades and pertinent debrief points. I had few beers with him over the years (including during my initial course), and the guy always had great stories that would make me laugh. I'll miss seeing him around.
I've found that of all the checkers I've heard horror stories about in 12 years, those stories turned out to be completely overrated when I actually did a PC or LC with them. That doesn't mean I liked each and every one, but they were generally fair if you came prepared.
I wish Mike all the best in his retirement.
