BertMcFish: The other thing - I have no stats in my profile, i.e. no putt stats, scoring etc. Any ideas why that might be?
Welcome aboard to the Wonderful World of WGT
Since you mentioned coins, I presume you play exclusively on tablet/mobile device. The other clue is exactly that -you have no stats - which come from playing the PC version
As far as clubs and upgrading, there are 100s of threads (well, there are lots anyway :)) that have suggestions
Most will suggest Wedges, Driver before Putter and even the WGT balls(like the 10cr ones) will show a difference in your game (notice I didn't say improvement - that's for you to achieve LOL)
