There was a tnation article from not too long ago where they worked the lats from the "bottom" position of the pullup with a lat pulldown. I tried googling it last night and was unsuccessful.
Here it is:
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
