to build upon some of what waws already posted. Delts...def see alot of guys who could look wider by bringing up the rear head...exercises, any of the various rear lateral exercises, this is one that I've always felt the reverse pec deck machine rear laterals might be superior to free wieght db rear laterals...Also very good...at the end of your delt routine, go light get the feel and focus on adding in face pulls and wide grip upright rows, wider than I see most others but also lighter, more controled and with a bit of a pause and "squeeze" at the top....
As far as Lats, yeah wide chins, pull ups, pullovers...but afterwards and inbetween sets Streeeetch the shit out of your lats, than PWO foam roll them when your lat training and stretching is done, loosen up that facia, allow them to stretch and pump more, and recover for the next time around. I saw quick width incorporating this a couple years back while everything else was platueing for me
