Timnator:
What can I expect? Is it a green speed thing?
Yep the greens are faster , so do some stroke play practice rounds and set the green speed to tournament . Also you may want to upgrade your driver , to the G20 lvl 81+, as well . This will give you more bang from the tee , as you will want more distance and loft , than what you are getting now. So remember the greens will be faster, so it will take softer putts to score well ,and you will get more roll , on your approach shots. Hope this helps. Happy Swinging
