Underhand and close grip lat pulldowns build width or thickness?

[Clubber Lang]

I know wide grip lat pulldowns make your lats wider (right?) but what about underhand and close grip lat pulldowns? Do they also make your lats wider or do they work your lower lats and make them thicker?

Here they are (underhand and close grip lat pulldowns):

I found that close grip pulldowns helped my back width without the strain on my shoulders that wide grip pulldowns caused. The only time I tried underhand grip was after my shoulder surgery and then I wasn't using a lot of weight, so I don't have any first hand experience with them. The most important thing to me was making sure that I used good form in all the movements I did for my back.

I noticed my biggest improvement in my back with the following routine.

BB rows 4x6
close grip pulldowns 4x8-10
rack deads or regular deadlifts 4x6
T-bar rows 4x6
I would alternate db rows with seated cable rows every other workout.

i like close grip pulldowns and pull-ups, they really let me focus on my lats and squeeze them on every rep, widegrip also tweaks my shoulder.
