My only input is some technique. Hubie Brown teaches this, and
everything Hubie teaches works...
Instead of arms held straight up and parallal to eachother, cross your arms at the wrists or slightly below, and spread your fingers out to better deflect and block vision. Put your X'd arms up in the outlet passers vision just like you would with parallal arms raised. The best thing about this technique is the elbow can't reach your face. Try it- have someone "chin" a basketball right in front of you, assume the X arms position and have them pivot & swing. Do it slowly with control so no one gets hurt. There elbows will still impact your forearms and/or wrists, but not your nose.
If they are real aggressive and try to throw the outlet over & through your hands, protect your fingers by making fists.
