This brings up the issue of low-energy go-arounds, whether with or without spoilers. In the case of our airplane (CRJ200), the thrust is brought to idle at 50' AGL. At that point the airplane enters the low-energy state. We are not expressly prohibited from, but are very strongly advised against go-arounds after that point, except in an extemely dire situation. In other words, you are commited to landing, smack it if you have to.
