...you can adjust for loft and flight angle so if you are playing into a gale at St. Andrews you can change the flight path of your ball to keep it out of the wind for instance.
Or vice versa of course.
But if I were, for instance, all of a sudden slicing the ball I can adjust the face angle of the driver to accomodate for that phenomenon until I figure out wtf is happening with my swing path.
You can adjust weight distributions as well in order to move the ball left to right or right to left so the club will accomodate different golf courses for you.
Need to fade the ball all day, a little tweak and there ya go.
There are something like 50 options on the R-11.
It must be stated that you have to have some idea of what you are doing for any of the adjusting to matter.
Naysayers comment that most common, weekend players set the club once and never change it which then leaves you with the extra weight of the adjustment unit in the driver head (although not much but it is there) for absolutely no reason.
But if you have a grooved swing (good or bad) a club like the R11 can be set to accomodate for shaft angle, face angle and weight distribution for that swing and you will gain distance and straighten out your ball flight with the club.
