Took my 16 yo grandson (about 8 or 9 HC) to leading retailer yesterday to hit some demo drivers.  TM SLDR, swoosh and Titleist 913 D2.  He hits them very hard, monitor showed little distance between the three, perhaps 3 or 4 yards at most. Hit both R and S, and lofts between 9.5 and 12 (adjusted up to 12 on the SLDR).  And all very straight, dispersion was minimal.  But consistently slightly right of center, perhaps (guessing) 7- 8  yds.  Shots were not blocked, swings looked right down the line.  Set up and Grip okay.  Tried SLDR with draw bias, understanding he doesn't have a slice problem but in the hope that the adjustment to a slightly closed face would help.  Short answer, it didn't.  He plays on fairly tight fairways in two leagues over a dozen or so courses, so  leaving everythin right can be an issue.  Any ideas?
