Well said!
As a TP, you don't need much to improve. Wait until you are a Master (longer tees) and take profit from the levels then.
For strokeplay like the tournaments your's playing, I'd propose for now to get two short wedges, a budget custom ball (Srixon?), and a fancy 3WD.
1) It's a real game changer to replace the Starter wedges which are the worst clubs in that set. A 50/75 yds combo or 60/80 yds, from L35 up, will serve you well.
2) Any custom ball from B-ES up will reduce the meter speed. Alas, they are subject to wear and loss and cause some steady spending.
I've been using the Tour-SD for a long time, but Srixon is even slower.
3) As a TP, a decent 3WD may serve as a driver, doubling the use of a budget club.
