ORIGINAL: v-snap
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...
OK to explain a little more. Maybe I use too much elevator for my snaps (I could improve that) but I also use ailerons in competition so the snap is fast enough and the plane does not have time to pitch up very much and I can manage to have speed left for the straight line that has to follow the snap. Now if I do exactly the same without ailerons, the plane has much more time to "pitch up" hence the fact that the snap looks deeper and as you mentioned, the snap takes more time to execute so the exit speed is much lower.
At a field with a plane handy as you said... Much simpler then!
