Can you just give us credits as rewards? Oftentimes, the balls you give away aren't what I normally play with, thus practically useless. I'm sure this is the case for the vast majority of players here.
With credits, on the other hand, you can decide what to do; you can buy balls or equipment of your choice, pay entry fees for certain tournaments... they can be suitably used upon your needs.
Please consider, WGT. 🙏
