QAD HD pro-similar to the Ripcord but I think it's better. It has lock down which means it won't bounce back up after you shoot. You can let down your arrow without the rest collapsing. It only goes off if you jerk it i.e shoot.It's fully contains the arrow and works without fail. I've had a few different rest but this was by far the best. I heard a lot of good things about the limb driver but it's not full containment but some don't care about that.
