GG2shots:
I have been playing WGT for several days now and enjoy it. I am a current level 47 PRO with an average round of 76.7. I have noticed that when I play other members that are lower level or status they still can get much more distance off the tee than I. I have earned 500 credits since joining WGT. How do I upgrade for more distance, or can I upgrade?
Now you are level 49 - notice how fast this goes!
In this game, distance and other characteristics (precision, spin, forgiveness) only come with the equipment, i.e. clubs and balls available in the Pro Shop. In your situation, I propose to start shopping with two short wedges, lvl 38 ATV (2x500 crs) or lvl 41 Ping (2x200 crs). They boost the short game tremendously.
If you are patient enough, the next buy might be the lvl59 G20 set (lvl 59 @88.500 XPs), excluding the hybrid. Instead of that, add a third wedge (e.g. 100 yds).
Add a putter only when you are sure to have practiced enough.
Eventually you might want some better (and slower meter) balls. Start from bottom up - my choice was the Tour-SD then (65 crs per sleeve).
