Hi, AFAIK there are no automatic upgrades as you tier up (clubs or balls), if this is what you
are asking. As you gain more experience (i.e. advance levels) more
and more equipment will become available to purchase. In terms of equipment and balls, you should have plenty to choose from at your level... you just need credits (purchased or earned) to buy them in the pro shop. You can also do a search in the forum on equipment, balls or clubs to get good suggestions for what to buy at your skill level.
Good luck and enjoy! -Keith
