I made my first and only hole in one on New Year's Eve 2019 - I didn't post necessarily because I didn't use a ProV1 for that shot (a Z Star), but I certainly used my 716CB 6 iron.

It was 169 yards, cool damp conditions in the mid 50s, probably playing all things equal about 175 yards - started just left of the pin and slightly drew back (I'm a lefty), landed softly and trickled in the right side of the cup. Still the greatest nine holes I've ever had - four birdies and a HIO.
