In other words, it is not a "safe wing" IMHO
I think I can honestly say I have taken that particular wing further into the envelope than 99% of the people in this forum and I'm still here to write about it. The one percent of the people who've taken it further than me were well outside of the published limits. It's a supercritical wing, it demands respect and it does have sharp corners. However, those sharp corners exist by definition at the edges of the useable performance of the wing and the AFM is written to keep "joe pilot" out of them. It is a safe wing if it wasn't I can guarantee you that my counterparts at TC and the FAA would have the fleet on the ground by now.
