as demonstrated, the fine line between rope and 'curveball' is so thin as to almost be invisible! thats a great example snap.
the main indicator of you practiced skill here, imo, is the way you avoid the easy shot and fly hard up the rope.
to some it mght look like 'HEY now, but if that ki84 was me i wouldnt miss'. thats not true because i know the pilot concerned is a good shot, and practiced in ki84. the main thing is humble was forcing him to either break off, or go for a difficult stalling shot.
great film.
