We spent this whole class going over the arm wrap grip. This surprisingly useful grip is often overlooked on the ground. Here are two of the options we looked at from one of my own videos.
We didn't do the lateral drop version as a group, but I had some of the taller students try it in place of the the firemen's carry.
We used the same grip to sweep from butterfly guard and dogfight, and as an escape from knee on belly. Of the techniques showed obove, these most resemble the spider guard version.
