For Scotty to say 'he was in a bit of an accident' is like describing Everest as 'a bit of a bump in the ground'!
Be patient with him, as a result of the accident what he is thinking and what he is typing are not always the same but he is a very smart guy working with Chris Welch who I believe is not so much at the cutting edge of bio mechanics but the guy who sharpens the cutting edge!
One thing I will warn you of now though is that just the same as you teaching pros charge someone for a lesson, Scotty does not give anything away for free so can only talk generals rather than specifics.
