I'm afraid that your choice of wedge (54°) was unfortunate - the shorter ones are more important.
You can do something soon.
At L39, you might drop the Starter 3H and get yourself the ATV 60° and 64° wedges. (The L28 Cleves if you want to go the budget way).
This is intermediate, too - for real zzzipping backspin, the top wedges are necessary, together with top balls.
Plus, the "slow ball" path is an expensive path. It might help to save big bucks if you try the Tour-SD, Srixon or L33 Cally and learn some faster meter speed.
