lat=wing
currently i am doing more than 90 degrees at elbow.(maybe 110-120
degrees)It might feel awkward at the beginning.
And I suggest that you do not try this variation unless you can
first do at least 10 slightly wider than shoulder width
pullups.
Nothing is more pathetic than the sight of someone doing wide grip
pull ups on the assisted pull up machine with a 10cm ROM...and
usually he has no wings to speak of...
