I Personally have spent hours in the pro shop comparing clubs and balls and stats etc. after all that work i decide i want to wait till i hit level 53 so i can buy that one club. It would be coll if i could place it in a wish list. That way i dont have to try and remember it for the next two weeks while i rank up...
This would also allow WGT to automatically remind you or notify you when a club in your wish list becomes available or when you have enough credits to buy that set you wanted.
