I think the only problem with the Concession Pro was the issue with the shaking up of the beer during the rounds of golf which was addressed in a CYBK PR. Now take into account that a high majority of golf courses use beer carts and their revenues depend on the golf cart beer sales. I did DD about golf course revenues and beer carts as well.
If there's some kind of skin / silicone coating for the golf balls that would make them fly further, then I see a huge market.
You need to let CYBK/XSKN know about that idea. Put your name on it first though. LOL
