You should be able to gift these balls whatever level you are!!
I purchase over 90% of my credits.
If you win an RG surely your winning credits other people have used to enter these tournies.
WGT have taken there slice of commission off, and the same with Matchplay.
Obviously there will be a few exceptions where some really talented players have managed to Grow the credits they received for advancing to tour pro, and managed to grow them into a vast sum of money. But I would think that is a very small percentage.
Anyway I just wanted to send some as a birthday present and a Thank you, I said i'd wait till I was a Legend, but now I just found out even Legends can't send them to each other lol.
Crazy!!!
