I'd watch out with that. You will get away with it with a loose or poorly executed pin. However, a well executed pin you are liable to injury your shoulder trying to roll out of it.
I change a potential shoulder injure for the ability to avoid a beheading any day of the week. And there is always someone who thinks his/her pins are awesome...

BTW, people is escaping from omoplatas (which is a thighter pin) rolling and nothing happens.
