another question since i'm here. when the balls in play run out, cannot wgt upgrade to offer us the choice of already bought balls in our inventory. instead the game takes a player down to blank balls. i know the simple answer is keep more balls in the bag. this happened to me, i found myself playing a decent round (for me) ( i was purposely finishing the callaway S balls, to start with the Zs) and i ran out of callaway S, not only did i have callaway Zs in inventory, but i also have wgt balls. i finished up unsatisfied and frustrated, playing with blank balls.
