Very interesting comments from all. I'd prefer ALL IN since it is logical that your ankles have a better chance of surviving. That said, ALL IN does not necessarily prevent fractures or Achilles tendon injuries. It will also require a different way of skiing and it will be hard to accept for some. Stealths were supposed to be the best Fogmans ever. With more user-friendly boots they could be just that. I do believe in a one plate systems as well, so if something should release at all, then the whole plate with both feet in. I think OB4 will be a super-interesting alternative to Reflex, for all of the Reflex front people. For double hard-shells...time will tell, but I'd still put my money on some future version of Fogmans/Stealth, with a better and more precise release mechanism (snow-ski like), while keeping the possibility to put whatever we want on the plate - Fogmans, Stealths, Powershells, or Reflex boots. In the meantime, I'll stick to my not-that-old Fogmans, on a custom carbon plate, hoping that the bone-crushing fall will not happen. The issue of pre-release must be tackled also, since it is equally dangerous to a non-release situation. Or, according to some pros - way more dangerous!
