Ira,
I do not think using a caddie is cheating. Contrary, it is an accepted part of the game. However, the one aspect where a caddie is allowed to assist that I do not like is in lining up his or her player. I am okay with caddie and player discussing where to hit (either putt or otherwise), what club to use, or how to hit. But, I do not like to see (and I usually see it on the LPGA Tour) the caddie standing behind the player guiding him or her until the caddie feels the player's alignment is correct. To me, THAT feels like cheating.
I don't mind the collaboration prior to setting up and hitting, but collaboration in setting up goes too far, in my opinion. I feel the player must set up and stroke the ball entirely on his or her own.
