There was talk in the industry back in the late 80's of the possibility of helmet manufacturers changing over to LBDs in order to increase the integrity of their product. This idea was squashed due to the fact that the LBD made the helmet almost bomb-proof and would ultimately result in a large reduction in helmet sales. It would have aided riders immensely but would have crippled the helmet industry so they decided to stick with the IMD (Inferior Manufacturer Decal) sometimes called ISD (Inferior Stock Decal)... depends on which coast you're on.
LBDs are, as has been stated, nothing to take lightly. As it relates to the PUSH LBDs, if you look at the sheer size of that logo, it goes to proof of the structural integrity of the entire fork/LBD relationship. The price of the fork reflects and testifies to the power of LBDs.
