Those are Pro-series bindings. I am not 100% sure about the year, but I estimate around 2004 or 2005. Those were back in the day actually the high-end bindings, glass-filled Nylon baseplate and hibacks.
they are. all the benefits of a Flow binding; quick entry&exit, energy transmission in your turns through the steel cable and the 1-piece footstrap and more comfort.
on the downside, they are very heavy compared to the newer models and don't have quick-adjustment ratchets. Some newer models also feature the Active Strap (NASTY) system which makes getting in&out even easier.
