Regarding reviews... I always have an ANNUAL review on a voluntary basis usually in Oct/November in readiness for the winter weather... incidentally the guy who reviews me (and insists on this technique) has "luckily" stayed alive for over 17,000 hours (yes thousand) in GA aircraft, not long haul airliners.
I believe that the Trevor Thom basic training manuals recommend this technique also.
Regarding older designs, for example be careful of the early taper wing Warriors... I flew a 150 and it wanted to drop the right wing on the stall... I held it level with the mythical opposite rudder!
I believe a pilot not sufficiently aware of this technique would get into a lot of trouble... Warriors are difficult to get out of a spin.
The problem seems to have been addressed by the engineers and the later 160s don't appear to suffer the problem. I have noticed a low fence on the right leading edge of a sister 160.
I still maintain there are no hard and fast rules and your perceived sticking to a rule "set in stone" could be more dangerous than my feet pushing the rudder bar.
Perhaps Bookworm can help here
