The fact of the matter is that none of us is good enough to worry about any of these imperfections in the greens.
Really?
Peter, I can't speak to the ability of everyone on the site, but of the GCAers I've played with, the one who actually probably
IS good enough to worry about imperfections in the greens is the guy you quoted.
When I was in California in the late '80s through the mid '90s, I seem to recall a lot of places having problems with disease on the greens, and it was thought that metal spikes were one of the contributing factors. Are there are any superintendents on the site who can speak to the difference that soft-spike or spikeless shoes have made with regard to the spread of disease?
With regard to the Eccos/Trues, it seems that they tend to leave visible imprints on greens, yet I never actually see their imprints upon reaching the next green, which is to say that while they may leave an immediate impact, it would appear that greens bounce back pretty quickly. I played a lot of golf over Labor Day with some GCAers, most of whom were wearing Trues. By the end of the weekend, the dirt cart paths were covered with True footprints, but I don't recall once noticing their marks on the greens, which would be consistent with my theory. Seems maybe there's more smoke than fire.
