Good for you, bg. As long as you're happy with them, why change, eh?
That being said, you will soon feel the urge to upgrade your equipment as you progress to legend tier & beyond while the courses will become longer & longer along with greens much much faster than what you now play on which will require higher flight trajectory in order to make the ball stay on the green. In other words, the clubs you have won't be good enough for you to compete in higher levels.
If I were you, I'd simply keep on playing with what you have now (plus keep on saving credits) and as soon as I hit L99, I'd buy myself the TaylorMade Set (L99+) which includes TaylorMade Stealth Plus Driver (L99+), TaylorMade P790 Iron Set (L90+) and TaylorMade Spider GT Notchback Putter (L94+).
Good luck and have fun on the way.
