Should there be a poll where you can select more than one?
At times, the driver gets me trouble and 3W sometimes ends in a super thin shot, but they still feel "comfortable" to swing.
My longest iron is the hardest with the second longest being a close second so 5i and 4i. Luckily, I rarely ever need to use them, and if I do, I get these really low screaming shots on the course. Even on the range, these two clubs are like a hit it once, hate the shot, then pick another club to hit.
Rick, there's plenty of evidence.
Players have stood by greenside for a few years now while their fellow competitors play shots to the hole and they have plenty of time to go mark. In fact, since a fellow competitor has to wait, you don't even have to be right there - you just have to reasonably believe there is a chance the ball could assist the play of a fellow competitor.
The evidence is not non-existent, and it is growing.
In my experience, the people that do it wrong often falls into two categories. Those that don't know how to do it and those that don't care. The first category we will probably find everywhere. The second might depend on the country, area, general state of the course, what kind of people that play it. Many that I've played with didn't know how to do it properly. They might have learned it at a course once and that information might have been wrong. Or they just do what a lot of others do. They're typically happy if they level out the spot, without regards to how they did it.
From my experience, people don't want to treat the course bad and most thank me when I explain how to do it properly. Some might thank me and not care the next round they play, but that's tough to do anything about.
My advice is to tell everyone you see do it wrong. Give them a demonstration and explanation of why it should be done this way. It can also help to reach out to the clubs and make them throw up some posters, roll the proper way to do it on screens in the club house. I once played on a course where they asked everyone that showed up to play how to fix the marks. Before letting them out to play, the players had to give a small demonstration. This can be a great way to reach out to a lot of players, but make sure it's done in a positive way. Some can fussy if they take it as a personal insult that you don't think they know how to repair the marks.
You find most golfers on the golf course. A very small percentage visit a golf forum.
My 60° Vokey wedge is black. It's black because, well, it's the only lob wedge we had in stock at that time. I don't like it or dislike it any more than any other wedge, although I can find it easily in my bag.
