Laminated Horn/Sinew Bow Technology

Grozer has been selling bows made with the biocomposite technology for a couple of years already: sinew plate/fiberglass + wood core + fiberglass/horn plate.  Lately, they introduced new shape to their biocomposite bows.  I am curious if SMG will update their laminated horn bow technology by incorporating a sinew layer on the back side of the bamboo core.
