In the event that your shieldbash was slightly off and you end up next to an enemy, you can aim your shieldbash for a fourth or half a second. I've been able to shieldbash enemies on both sides with this, and since you're no longer moving they fly quite far away.
tl;dr: spin immediately after shieldbashing for AOE
