I've been playing for about 4 months, and I'm in the market to replace my current regular flex driver with one with a stiffer shaft. I went for a quick, informal fitting today, and to my surprise it turns out my typical clubhead speed is in the 105 to 107 mph range. Would I be better off buying a stiff shaft which allows me to load it better, or going with an extra stiff which gives me room to grow as my swing mechanics improve? Thanks in advance!
