I have been looking at the post impact exit path and cant find any difference??
Would a difference appear in flight results from different spin axis and/or effective loft for the ball launch from each clubface?
The clip is not really long enough to show the difference… but if it was longer you would see it to some degree.
Long irons would send the ball more offline while shorter irons would tend toward more trajectory issues due to the deflection patterns created by off centered hits.
