Hi,
unfortumately balls tend to get lost during a game (as in real life), and we may need new ones. In real life I would have quite a few balls in my bag, but in wgt I can not use other than the wgt-standard ball if the one in use is lost or run out. In these cases itr should be possible to pick up one of the other owned balls, not only buying new ones (takes too much time during match-play).
Best regards,
Roschad
