Using a line on the ball to assist with putter aim seems to be common practice among many tour professionals. My understanding is that you have do some other "things" correctly to get the full benefit, but it can help with "side-of-the-ball" versus "behind-the-ball" visual issues.
I'm curious as to how many of them also use it on tee shots to assist in their alignment? Seems like I saw Tiger tee up with the line parallel to the clubface for a tee shot at Dubai over the weekend.
Alignment is such a key aspect of playing it would seem that any chance to let your equipment help you out would be worth the effort.

Using a line is becoming very common both on the greens and off the tee.
On tee shots some Pros have the line parallel to the clubface because looking down at it bothers them visually.
However, I would not take a manuf. at face value that the line is in the best location. If you put one of the most popular balls on a "scope" you will find that the line on the ball and the "scope" do not often match. Because of this, I am aware of one pro who wants all the balls he gets scoped by the manuf. before he gets them.
