I have flown with both Mike Green and Jon Lane and would heartily recommend them both. I would also add that Jon Lane is not a risk taker but a very measured and professional pilot.
I'm sure there are a lot of good FI's out there who still do them, see the names mentioned in addition to the more famous ones. As for whether you should do EOL's in the R22, I think the answer has to be yes. A student/pilot doesn't want their first full down auto to be for real.
Draco, I would also vote for Glenda but the last I heard, she was in sunny Hawaii. Obviously the draw of the Midlands wasn't quite enough...
