Have a look at this open hand back hand strike. It is on target in a snap. A great infighting strike, but can be delivered as a straight offensive technique as well. It hits VERY hard and is a stopper. Because of it's arcing delivery, it will hit high on the side of the head, near or on the ear. I like it coming off the elbow strike. This is a strike you want to have in your ammo supply. Practice it using both the heavy bag, and the striking mitt. Needs very little room to explode. NASTY !!
