Had a successful arm bar from modified rubber guard. Instead of foot planted on hip, i had a hook in which worked out better because my lack of flexibility. So I gained "retard control" with a hook in and was able to transition to "chill dog" and remove hook to bring it up to lock for an "omoplata" attempt. Because Op was defending very well I had to transition to an arm bar which worked very well from this position.
Also learned an alternative escape from side mount where you rotate away from Op and sit out to turtle and drive back into Op.
