One of the guys in my regular group got one of those awhile ago. His iron and short games are incredible, but hitting off the tee has always been a struggle for him. He just has a naturally steep attack angle. Obviously works for irons, but not what you want with the driver. I think the mini works for him because it’s basically a hybrid driver/fairway wood. In reality, he doesn’t really need it, because he has some 3 hybrid he bought a thousand years ago (for real, might have been when they first started making them) that he can hit anywhere from 180-255 on command. But, when he needs a little more off the tee, the mini works a lot better for him than the 445-460cc drivers.
