Hi Glyph,
Sorry bud, but after being on this site for 15 days - what do you expect.
For a start as someone already mentioned - you dont need to buy any clubs right now. You need to learn how the game actually works, and what your clubs can and cant do. Thats gonna take time. You're not going to win tournaments from the get go !!
You should be able to improve your game considerably with clubs you have - but its gonna take some time and practice.
Thats how the best have got there. Check their stats out. 700 - 1000 ranked rounds, and just as many in practice. So - get practicing, and see your scores and positions start to improve.
One tip - take as many notes as you can on each shot / hole. That is key, so that the next time you come to play that hole or to play that shot you have some data to work on. In the end its all maths and practice.
Stick at it, you will improve - but give yourself time.
Cheers Doug
