Starter balls work well with Starter clubs but result in a quick swing speed with custom clubs. Some players deal with it, even like it, but most of us must switch to pay for their balls. You may know that they get lost and have a limited number of strokes, generating a steady income for the company.
Good thing is, you can start at the top of the list, B-ES make a difference! Tour-SD, Srixon and L33 Callaway are a tad better.
Concerning your desire to spend on clubs, there's a caveat: I see that you don't play a lot though you're a long time member. Spending on clubs will raise your game and your tier, resulting in the need for other, better (longer) clubs. Careful what you wish for!
That said, may I propose The L58ish Ping irons? It's good quality, high trajectory(!) but not too expensive.
More important but higher in level are good wedges. Consider a set of 50-75-100 yds or 60-80-100 yds, like the Titleist Vokey from L76 (NOT the 52° below!). Drop the Starter hybrid.
Have a look if you have a "Beginner" putter in your bag - it may be better than the Starter, and it's free.
These clubs will bring you through Master and Tour Master, and once you think that you're putting better than your inclusive putter, consider to buy one.
