Hey andyson,
thanks for your answer.
But today I played two 9-hole-rounds, starting with new balls and then a 18-hole-round. After hole 11 I already needed a new ball and the reason wasn't a stroke in the water ... ;-))) I hope I didn't forget one 18 round, but I don't think so.
For me it feels, the bug isn't fixed ... But I apologize of course if I'm wrong.
I'll have another look at the durability of the balls. :-)
Btw: I always buy 30 balls and I still have some Callayways in my bag, which I use every 4th/ 5th round ... ;-)
Best regards,
Robbie
