Finally, two good responses which are helpful rather than just biting back. Yes, you're right, I was playing ranked rounds, that is why I was getting upgraded. I do want to get better, but not by putting money into the game.
In real golf the difference between a 15 handicapper and a 8 handicapper is definitely the short game. But the difference in WGT between a good score (e.g. 60) and an average score (e.g. 67) is not the short game but by getting the ball to do what you expect it to do and stop close to the hole. You don't get a score of 60 by improving your chipping or sand saves (unless of course you sink them).
I finally managed to get a survey done last night which got me 450 credits. Still need another 1400 to get the clubs I want. Has anyone done the CreditExpert offer? Looks free, but I'm not 100% sure. I have read the small print but still can't be sure. That would get me damn close to where I need to be.
I agree that there are unlimited free balls, but, as I keep saying, they don't do what you expect/want them to do all the time, and so you do have to pay for new ones for consistency.
Anyway, thanks for the advice, somthing to think about.
