I should think so. A Reball training center sounds great for teams, but as for the owner...
The no mess factor is a big selling point, to be sure. I've played indoor fields that were downright dangerous. Everything was covered in a stinking, slippery slime. However, the field made money, and that is a prerequisite to staying in business. It seems to me that Re-Ball removes much of the profit potential of an indoor field.
Any Re-Ball training centre owners care to comment?
We're lucky to have one over here in NZ ... but only just.
The owner has an indoor go-kart place, and put a small field in for local teams to practise at ... means we can head down once or twice a week to shoot at much lower cost (and means that the actual paint training we do can be more focussed on actual games and stuff).
Without the go-karts it wouldn't fly at all - the overheads would kill it (especially in such a small market as NZ).
