Total Plan??

Hanging tend increases length and tends to increase girth at she shaft.
Ulis increase girth and tend to increase upper shaft girth.

Are these statements totally accurate and would it be possible to make even, solid gains using only these exercises?

Read posts about Bib’s history. He spent many hours hanging to gain length and base girth, then did an extreme form of Ulis to increase his mid and foreshaft girth.

Yes, those exercises can be sufficient, but you shouldn’t do them at the same time. Ulis will make your shaft too sore to hang.
