I'm familiar with getting to a leg reap position from and open, unclinched butterfly guard, but I'm having a hard time translating this when I use an overhook. You have to elevate your opponent, then let go of the overhook and pummel for an underhook so you can get to his legs, which I find usually gets me stuffed. Do you guys have a better way of doing it? Or do you just not go after the legs when using an overhook?
