Have you tried going back in time and learning to block? If so please share how to with me because I've got a massive nose that people love to punch xD
I've seen face savers work for most people but for me they always gave me more trouble, I've possible got a weird shaped head? Lol. If they were tight enough to stay in place I'd get headaches even when not really hit that much, or I'd be wearing a facesaver because of the massive shots I'd be taking and I'd have headaches from that. Or the best one ever was when I wore it a little loose and the bar of the face saver was punched into my nose, giving the inside a nice red paint job.
I always get hit less in minimalist headgear because I can see more, read the shots, and respond properly.
I think when you wear big headgear your partner can also get a false sense of your safety and can end up hitting harder than they would otherwise.
I reckon head gear with a mask would have done me well, but I still haven't used one yet!
