Back'n Wrap

I was playing with wrapping the kimono around my opponent's arm the other day and two possibilities appeared.  Now they need some refinement but here's what I've got for now:

• From the guard, after wrapping the arm and attempting to pull it across for the armbar your opponent resists by pulling their arm back toward their body.  Adjust your wrap to further encircle the arm, then assist their motion and push their arm to the body, then set-up the triangle over the manipulated arm and switch to the opposite triangle.
• Again from the guard, wrap their arm, and pull for the cross arm lock.  If they defend, pass the gripped part of their kimono to your other hand, which has either gone behind their head or (if you have excessively long arms like me) their back via their opposite axilla.  Now post with your free hand and look for rear mount as you rotate them by pulling on their kimono.  If you have passed the kimono to the arm encircling your head you can choke them with their kimono by sliding your newly freed hand down your forearm on the side most proximal to your opponent.
