I played with many who pull the pin on all approach shots, and land 30 feet from the hole...kinda funny...
But, during the WGF Tour, I had the pleasure of playing many rounds with Zant, who also puled the pin on all approach shots, his reasoning is hit one stick and you are out of a bird opportunity...and Z was always around the pin.
So I do when I remember too, but often forget.
And, I recall a post a few months back that someone had won the Crystal "hit the flag stick award"...something like 1000?...I think, and one of WGT's better players said congrats, I've only hit a few...but I do have 1200 hole outs...
Food for thought:)
