Db rows and close grip chin ups build the lower lats and tie in's, and some thickness but don't build width.
Wide grip Lat Pull downs and Pull ups build width.
T-Bar rows build thickness
Chest supported Rows- High,seated, low are a form of isolating the row.
All of these are great for what they do as long as you feel the lat doing the work. If not you are using to much weight and using momentum to do the work not the lat muscle.
Very easy to have the Bi's, traps, legs and delts take over.
