These add variety to your offense and will keep your opponent guessing. You will use the Scorpion shot the least unless it is against someone on their knees or another smaller fighter, but knowing it will help you guard against it being used on you. The most difficult fight I encounter is one against another small stature fighter. I compare it to two left handed fighters on the field. An important note is the attitude you may encounter while on the field.
Some larger fighters feel differently about smaller fighters than about someone their own size.
Including how hard they feel someone should be hit or how hard the smaller person has to hit them. Don't let others call your blows for you. If the shot is good by YOUR standard call it, otherwise let them know it wasn't good. They aren't in your armor so they don't know how the shot felt. This tends to be a common problem with smaller fighters.
