If you want the glitz and have money to burn, a high performance ball might be a choice. It is state of the art technology - at a price.
If you are 150 average, a current ball will surely improve your game through pin action. But this does NOT have to be top line ball. Normally, current balls have enough potential to fit your game at reasonable prices.
Try a mid-price ball first, or a used high-performance ball (but this can be risky).
At any rate, seek out advice from pro shop. Let your game be studied, or show your current ball and describe the lane condition you normaly play on. A serious pro will give you matching recommendations, and a proper drilling to your hand, style and lanes, too.
