Thanks LR,
I ask because people exclaim that they must equalize on the way down, however I never see them having much difficulty and I'm wondering if I'm odd.
Moving my jaw works most of the time for me, however I've had to Valsalva my way out of a few relatively shallow descents.
In my very unqualified opinion, pain in the center of the head on climb is likely sphenoid-related reverse-squeeze or translated nerve pain.
Have not experienced that but have had my fair share of eyebrow pain - which I'm also very unlikely to forget.
