Tom Paul has some wistful remembrances about certain "ball above feet" tee boxes in the old days that set you right up for the "goin' draw" that was needed.
In Texas, we call the goin draw a runnin beauty duck hook.....
I recall a renovation project where a well known Tour player was a member, and he said that "Everyone knew" that you never line rectangular tees up partially staggered, i.e. where the right side of the forward tee is inside the left side of the back tee. Apparently, as Tom says, this is quite a visual distraction for the best players in the world. I would have never guessed that, since the back tees are merely a rumor to me as a golfer.......
Most tend to believe that you can get away with more misdirectcion with rounded tees than square ones. In other words, if you build a rectangular tee, most feel it ought to aim to the center of the fw, whereas you expect no directional help from a round or free form tee.
That said, even with round tees, I find I can use any angle or orientation providing the furtherst point of the front curve is on line with the center of the fw. That seems to orient the bow of the boat, as it were, and intuitively line players up, even if they are on a part of the tee that points well right or left of the target.
