I agree with the first part of that sentence. I chopped off two inches a few years ago, and this year I've been choking down another full inch (at least) on the club. I've never drove the ball so well in my life. I'm reading a lot advice suggesting get flatter, but I think getting too flat was a problem of mine. Which, I suspect, was a result of the driver length. With my driver at this length, I can turn my shoulders on an angle that feels pretty similar to a 4/5 iron.
