BB cleans & HI-Pulls, which also hit the laterial and rear delts very hard. A prime back mass builder, sort of like a super charged upright row. Your shirts will never fit the same again and you will look like you could walk through a wall. Weighted chins with the thumbs facing you. If your lucky enought to have a set of gymnstic rings (the ones that turn as you use them) then use them and drop all other forms of chins. The rings allow a more natural function (twisting the wrist/elbow's,joints, etc) for chinning. More weight strapped on after time, the more the better.
The wider the grip the less recuitement of the lat's/back and probably more stress on the shoulder joints. A middle and even a close curl grip hit the lat's/back more directly. Good Luck.
that's some good advice right there
hitting chest tonight, but will use the bb cleans and hi pulls
