The response to the U+ Crazy Light/RBZ has proven that light and mobile is what the people want. Military grade shoulder pads are overkill for most recreational players and no shoulder pad is guaranteed to prevent injury all-together. I think I understand what you're getting at, though. However, there are still options out there that are more protective than RBZs, but to justify high end price tags, the industry is selling performance or at least the illusion that "product x" will enhance your performance. It's the same as Jofa selling the illusion that their gear would enhance safety. The bottom line is that every player has different needs. There are plenty of ways to add protection if retail offerings are not meeting your needs.
