I play with some of the best players in the world. The higher level clubs do make a difference.
Not really because the best players in the game can get it done with the starter clubs .Anyway what you need to do is practice more and learn your clubs .Also work on your short game . With a 78.66 G.I.R, you need to work on improving your short game . Work on the punch flop and pitch shots . Get your avg. to pin down from 14ft. to 11ft. making your putts easier to make .
A good short game is what will make the difference for you . Learning how to attack the pin and getting closer to the pin will improve your scoring more than anything . You have a great set of clubs now so learn how to use them . Play some stroke play practice rounds and work on the weak parts of your game . Although it may seem boring its a great way to get your game play together .
Start by using the free ball and the mulligan feature just to get the basics down . Then switch to your normal used ball and fine tune your game from there . You will definitely see an improvement in how you play . Plus you will be earning XPs while you are practicing and playing .
If you cant play a good game with the clubs you have then you wont play a better game with the ones you get . No club is a magic wand no matter how much we want them to be . So take some time and put some practice in . Your game will get better if you do .
