Exactly. And with this, they could sell the same balls again without having to produce new ones.
OK joking about the last bit. I know they don‘t need to do anything to produce the balls... although... with the prices of some of them you‘d think they were real balls.
Seriously though I think it is a great idea. 150cr too high though. Because you‘ll end up with dozens of random single balls. Difficult to actually use them as you don‘t want to end up using starter balls mid-round all the time.
So I think it would even be profitable for WGT at around 50-100cr since there is a good chance the found balls won‘t ever be used.
Here‘s another idea: how about lake balls in the pro shop. A dozen random balls with random shots left for 300cr or a dozen of the same brand for 600cr.
Or this: When losing a ball you get the option of waiting (searching) for it for three minutes and a 50% chance of finding it, this for say 40% of the price of that ball.
