You make very good points, and for the most part, we do agree. I assumed you started after high school, it was the 81 that got me, that makes me old enough to be your dad.
When Dave Feldberg is on the the third card, and gains a significant advantage on card one because there is no official on card three, you still have a problem. I don't say this because I think Dave cheats, only because I think he poses a serious challenge to the players on card 2 and card 1. The truth is that if you can get caddies at majors, you can probably cover every card. It's the lesser tournaments where you go lacking. Perhaps that is good enough?
Given there is often enough video to provide evidence on most cards, perhaps video review or video based challenges should be allowed?
Perhaps it is my age, but my faith in integrity is less than yours. I believe that we should be honest, and play by the rules, but as a certified soccer referee, I see far more gamesmanship than an actual desire to follow the rules. Trying to get every advantage - legally - vs cheating is a slim distinction for many/most athletes. One only has to watch television to get this very quickly. My feeling is that the rules should enforce integrity, relying on my fellow human beings integrity seems a bust....
