Wutpa: I'm just curious. You consider standard greens to be an advantage?
rather ridiculous not to think that.
Slower greens have less break.
Recovery shots have less roll.
Can ram putts even harder without worrying about how far past the hole they go.
Now if you're used to playing 12s or 13s or whatever else and that's 95% of what you play then dropping down to 7.9 is going to cause you to miss putts.
But that's because you aren't used to reading the lines.
if someone is hammering out red tee rounds one after the other they will get the break down on those greens and will score better than on 12s on certain courses. Kiawah and Merion are good example os this and those are the two most common that's used for that. others it doesn't matter that much.
Mobile players are used to bouncing around different green speeds each round but even then quite alot of us don't like 7.4s. (tendency to over read the break)
BUT as i said if that was all i played they'd be the easiest
