I was playing in a paid tournament and I was having a great round (-5 through 12) and I encountered the last "hit" on my extra slow meter ball. Obviously this was poor planning but it happened. I was thrown immediately into the starter ball and the meter speed went from zero to 100. I know that you have the choice to buy more of the same ball when this happens - but why cant you change your ball to something else in your inventory mid round ? I had several Pro V1s in my bag and I cant figure out a way to switch them in. Is your only choice to finish the round with that starter ball or buy the same ball you had been using ? I finished at -2 - had one blow up hole, its a significant change.
