Here's an idea I wanted to throw out. Can you create some sort of mechanical adjustments to existing clubs (for a modest amount of credits) that will "tweak" your current clubs in a beneficial fashion? For example, I use the high-end R11 irons - great clubs all around in every aspect...except for a greased lightning meter. What if, for a sum of credits less than all new clubs, you could add something along the lines of a weight or a balance that would improve the clubs in some measurable fashion: precision, meter speed, forgiveness, etc.
Seem doable?
