Personally if you stick your elbows, the blunt force is more concentrated. I have cut guys with sticking elbows and ht eother ples was that it jarred them. If you drag the elbow, the force is diffused, even though you can cut the other guy. I prefer being able to cut nad jar the person with one hit. also by being able to stick the elbow you are more compact and have a little less risk of overshooting and getting trapped. IMO
