Bump...brand new Head/Tyrolia RDX plates are still available! Priced less than a half of suggested retail.
..Features a very simple and yet elegant design that hasn't changed for many years. This "light" free floating system probably offers the least intrusive plate option of all that's available by Head/Tyrolia, Atomic/Salomon, Rossi/Dynastar, and Volkl/Blizzard/Nordica. They work well with all bindings including non Tyrolia ones, by helping the bindings remain in the constant BSL.
All my current FIS and non-FIS Stöckli lasers are mounted with the RDXs, and they allow for such great edge angle and leverage without altering the ski's original flex pattern or causing dead spots.
