Close grip vs Wide grip chins

[Bullit]

Ok, I want some width, some wings.
Which is better close or wide grip chins (both in a hands facing each other position).
I have been doing 4 sets, 2 of each, but would prefer to concentrate on whichever one is more effective at widening the back.

I'd just stick with the full range of motion close-grip pull-ups. More compound, more to do. Add weights if you haven't been.

'Cause the farther you hold yours hands out, the smaller your range of motion.

WIDE GRIP CHINS WITH YOUR knuckles facing you....that will work on your wings...

Wide grip, oh yeah. You'll find some sore muscles switching to wides after doing closer gripped.
