Long ago, I remember asking in the CC forum if anyone had a clue about the width of the marker, thinking that it would be a good tool for dealing with crosswinds. Apparently nobody had thought of that before. That's when I started my experimenting.
I made my findings known, and several started using it. I'm not sure, but I think I put it up in the main forums a few years ago.
Anyway, like I say, it works for me.
Oh. Don't be put off by my fairways stats. There are a few out there that I miss on purpose, finding that a short shot from the rough can be easier than a longer one from the FW.
