They must be raving either about having C1 whiskered or perhaps the cosmetics of them. The first time I saw whiskers on a course both C1 and C2 were whiskered in different colors eye appealing, and nice to know the distance I was putting from instead of estimating, and fun for a first time. There was another course 17 of the 18 C1's were whiskered except for a basket sitting on a wooden block on a mound. There was one whisker on the wooden block next to the basket pole. No idea what that meant.
We worked with a couple park systems to get C1 whiskers installed. Like I said, many casual and tournament players thought they were great. We essentially did it to save us from marking C1 circles, for our A Tiers. Of course, several other clubs running A Tiers benefited as well.
They did not get too trashed by mowers, but they really lost their color. We discussed them lasting a couple years, with the parks. I am not sure we will get two out of them. Maybe different brands would fare better?
