Is the shaft flex on your driver different than the flex of the rest of your clubs? Even if it is, there is no standard for what a 'stiff' or 'regular' flex is. One of my co-workers has a TM R580 with a stiff shaft. He took it in and the shaft tested as a XX stiff. He now has a frequency checked shaft and everything now works fine for him! From your posts above it sounds more and more like you are hitting too stiff of a shaft. Take it in to have it checked where they adjusted your irons - this could fix all your problems quickly.
