pull ups vs. lat pull downs vs. close grip

[thatdamngood]

I know this was probably posted before, but I put a search for pull ups - lat pulldowns, and it gave me ****e. Therefore I had to start another.
Anyway, I do all three of these during my back workout. I seem to get a nice pump. I was wondering it might be redundant.
Here are the excercises that I do.

Pull ups, Lat pull downs (wide, then close)
Cable row
T-bar machine
dumbell row

Comments?

i would do pulldowns last, as a finishign movement, like this:


wide-grip pullups
bent-over bb rows
chins or close-grip pullups or 1-arm db rows (i like to rotate)
cable rows
lat pulldowns
