What's so good about Figure 8 slings?
They allow you to actually use your arm which alleviates muscle wastage.
They also hold your collar bone backwards so that it heals straight (not aestheticaly), meaning that your movement is not diminished once your bone has unified.
They aren't as comfortable as slings as they exert some pressure against your collar bone but if the choice is some discomfort whilst healing, bearing in mind it's going to hurt anyway, or permanently reduced rotation I'd say it's an easy choice.
