I tried it out in a CTTH and didn't like it.
I put backspin on my shots for a reason... I don't want the ball rolling 10-50 ft. For the vast majority of my 100-230 yard shots, I'm going to stick with the full swing.
I do play some rolling shots, though, and I might use it there... like ones where you are 180-240 yards out, and you can't stop the ball on a dime, and you can't land 10 yards in front of the hole either, because there is a huge upslope that will kill any forward movement... so you land it 20 yards short and roll it up the slope. One of the Par 5's at St. Andrews comes to mind, but I can't recall what hole it is. I could see punch shots working for that.
It might also work good in the 30-45 yard range... or from the rough.... or into really heavy wind at St. Andrews... I don't know, but I have no plans on using it from the fairway anytime soon, if at all.
