middle back/rhomboid development

[number twelve]

hey im trying to pick up the middle of my back, right between my shoulder blades... i do bent over rear delt raises, and pull downs from differant angles to try to hit that area.

i always change stuff up but my back workout generally is:

weighted chins 4 x 10, 8, 6, 4
deads 5x 8,6,4,rep out
rows (dumbell or barbell) 4x 10, 8, 6, 6
pulldown (close or wide grip) 3x 10, 6, rep out
rear delt raises 3x 10, 10, 10

ill substitue in T bar rows and cable rows every other week in place of barbell rows.
what more can i do to thicken up between my shoulder blades?
thanks

close grip T-bar would work well...just recently i went back to one arm dbell rows done strict and slow, stretch at the bottom...the next day the upper middle back is sore right between my shoulders
