What's sick is that you can finish it there or roll over and lock up a triangle from the bottom if you've got that kinda skill and put enough reps into it.
Never tried to finish it from the mount looks good.
A great way to finish it that I use a lot is kicking my leg over his body and turning yourself like you would for a japanese necktie. It adds a ton of pressure and you don't need to squeeze as much so it's sort of similar.
