Dear Whit,

"where extraction of the twist-3 matrix element $d_2^p$ is most 
sensitive."
I am not a native English speaker, but can you really say it this way?
(The extraction is not sensitive but g_2 in the kinematical region is ...)

-> in a kinematical region most sensitive to an extraction of the twist-3 
matrix element $d_2^p$.

The data was taken -> were taken

A_para and A_perp are not defined:
... with target polarization aligned parallel and perpendicular to the 
beam,

we will discuss -> "I will discuss" (you)

Best regards
   Michael
