Well here is what I did. I was flying behind an ASW24 in my LS6. We were comparing how the two ships performed while doing some wing overs and other stuff to burn off some excess altitude. At the top of the last wing over, the pilot in front of me rolled it inverted and pulled it in to a Split S. Without thinking about it too much I repeated the Split S a few seconds later. The rapid advance of the ASI towards red line was impressive and relentless. I pulled back some, nothing much happened, I pulled back some more, nothing much happened, I pulled the stick back to the stop and started cursing at everyone involved in this stupid decision, and finally the nose came back to a normal distance below the horizon rather than its previous straight down orientation. Nothing broke, cracked, acted weird, or got bent, but when I conferred with the other pilot on the ground, we both decided that we were not going to do that again, and we both needed a beer before going home.
