My impression from reading about the SLDR is that the position of the center of gravity on the SLDR makes the effective loft lower than the stated loft.  If that's the case, the 12 degree may play like a 10.5 degree.  To the OP's question, I am a low ball hitter and have benefited from using higher lofted drivers.  My TM R1 is set @ 12 degrees.
