This has been a good post. Interesting to read all the opinions on this subject.
I have to clarify what I said previously.
I would always use the Putter on the green except if i'm in a situation where it's just about impossible to putt. Like what's been said before St.a #2, in the valley of doom, in the front of green. Putting over that hill can be a disaster. St.A #17, when at the front of green with the fringe/rough between you and the pin. Just two holes that come to mind.
Somebody asked before how to use it.....
30yrd putt, using my C64 Wedge, Full B/Spin, Full Shot(60yrd)... Ding and Nike Ball. Depending on wind most of the time this would be awfully close to the hole if not in. I have also used it for a 16yrd Putt and that's about a 3 Qtr swing. Just remember wind and roll on green will affect this shot too.
The wedge shot on the green also counts as 1 putt on your card. Takes a bit of practice.
