There's nothing wrong with posting a question to the forum (that's what a forum is for), if the question hasn't been handled yet (which one might check via the Search box). The FAQ section on green speeds isn't explicit about replying to your question. In fact, it mentions 7 (!) possible green speeds, although I've only encountered 2 of them so far (standard & fast). It would be great if WGT let us choose any of the 7 green speeds for our practice rounds and, optionally, enabled for us to get "surprised" by any of the 7 green speeds (activated randomly) during our multi-player ranked rounds. It's just too monotonous to have to play always on the fast greens just because your rank is Pro.
I've just checked out the newest Tiger Woods Online Beta, and although the game is still unplayable for me (this time it's the shot meter freezing totally, so that I'm unable to make a single shot; and I happen to be on a different computer now), I've noticed that one of the things TWO have changed compared to the previous Beta is that you can now, when launching a round, select any tee, green speed, wind speed, etc. etc. etc. (These features were locked for beginning players in the previous Beta cycle.) You can even select the speed of fairways, or the hardness of greens, in addition to green speeds... There are at least 4 options to choose from for any of these characteristics.
It would be nice if WGT gave us similar options as well – at the very least for our practice rounds.
