Hi Russ,
All players are equipped with 2 club sets when they first join the game. The WGT Beginners are in your bag by default, but you can switch to the WGT Starters at any time. The Starters give about 10 extra yards per club on the average and are more precise than their Beginner counterparts. The trade-off, however, is a slightly faster swing meter.
Just load up the game cilent and go into My Settings > My Equipment to swap out your clubs. You can watch a video tutorial explaining how to equip your clubs by clicking here.
