+1 regarding the necessities at Master tier.
My additional thoughts do not apply to the Blitz and CTTH games which you mostly play. These habits, which are perfectly o.k., will not bring you to Master - stroke play will do the job!
To get some more fun in the full games than always play the Starters, you might want to get yourself a good 3WD as a replacement for the driver plus for a powerful second shot. I'd prefer the Level 58 G20 (495 crs) over the level 69 RBZ, high trajectory outweighing the five extra yards, and saving 100 crs.
It may also be time to get a custom putter, there are a few with reasonable pricing between levels 35 and 55. As an example, the Rossa for 725 crs.
Then, try a cheap custom ball, starting from 1 cr per nine hole round. (not for CTTH and Blitz if you act thrifty).
Alternatively, for the single shot games, you might add a third and forth wedge for more precise shots. Again, a custom ball with some spin dots might be a good help.
