Tom Wishon's books speak to this very subject---that the average driver length on tour is 44 1/2 " and most amateurs should be playing drivers about 43 1/2" ----gives you more control of the club, more shots coming off the sweet spot and thus, more distance. (as you folks have noted). Guess it's time to get rid of my 45 3/4" Adams driver!
