I love these conversations...I think I understand the initial question. The poor guy did an outside snap inplace of an inside snap..
Wayne never heard the term shoulder snap before. I know some full scale pilots would kick the opposite rudder to enter the lamchavak (easier said then spelled).
Now the response of "too deep of a snap with rudder only" lost me...If infact you stalled the wing it wouldn't be any deeper, one from the other. Now it may have slowed the rotation due to lack of aileron use at the onset and caused a slower airspeed at the recovery stage but I can't picture a deeper snap. Or maybe we are just now questioning what the high roll rate monoplanes introduced to the IAC world in the 90's "was it a snap or a roll????".
These discussions are much easier to picture at the flying field with a plane handy...
