Hi Mickey and first it IS a good move upgrading if you want to score better. BUT it does take time to adjust to new clubs and in particular, working out what distances each club goes with different spin and wind, 3 days is hardly enough time to judge them, or the game on that basis,
Your real issue is with the short game, and not surprisingly this reflects in your scoring. Have you read the FAQ on chipping, pitching and putting? If not do this before you swing another club as you are endangering your playing partners and players on opposite fairways because you probably have the tendency to throw your clubs after yet another duffed shot! The short game is the hardest to master, and your stats say you litterally stink at this facet of the game.
This is a great game and IS difficult to learn and play well but with LOTS of practice you will get there. Yes there are the odd shot that cannot be explained but this happens in real life golf too.
If you want a hit and I am available invite me so I can at least give you some pointers.
