It may be semantics, but there is no such thing as an adjustable loft driver. You can change "dynamic" loft however, by varying face and lie angles, or how you grip the club, shaft lean e.t.c. Its not impossible, just impractical as it would entail some sort of device within the head cavity that would permit moving the club face. and there may even be proto types out there than do that very thing. Today's drivers only allow one to change the angles the shaft enters the hosel. This was done decades ago with the wooden heads by boring "across the hosel". What's next....maybe gyro inside the club to retain loft regardless of your swing, shaft lean, or whatever...?
You should tell ranger that if your gonna penalize my group then you damn well better penalize the ones behind us that we cant even see. Dont ever slow down intentionally though because you can get behind pretty quick though.
