Usually a 7 or 8 iron, but wind in face, so chose 4 iron. Straight all the way and SMACK, off the pin. No-one in our 3-ball seen rebound, so we thought.....that could be in. I turned on my video phone for the 171 yard walk down to the hole and there it was! It had hit around 1cm of green front edge of cup and smacked pin flush, 1cm away from a 171 yard shot into a hole 4.25" diameter!!!!!
