Overall, these are really light, durable bindings that make skiing a fat ski (mine are 100 underfoot) much easier. I would recommend these to anyone at or under 200 lbs that wants a light binding for fat skis at a good price.
The Griffon, utilizing Marker's Wideride design, performed exceptionally well on my Rossi S5's. There was a noticeable change in weight and performance when i switched from my px14 race bindings. They were lighter and the wider mount points and wider AFD pad allowed me to control my wide skis much easier.
The look of the bindings took a little to get used to because the toe piece is different than most other bindings but they grew on me. The short mount points look slightly different but they reduce the swing weight a lot.
I work at a shop and paid cost for these, so at 135 bucks they were a great deal.
I am 6'0", 200 lbs. and an aggressive skier so a binding needs to be strong enough to hold me in. I was skeptical about the griffon due to its light weight and DIN setting (3-12) but I couldn't be happier. I had NO unwanted releases. They ejected once during a pretty serious spill, that's it.
I ski hard and have had zero issues with these. Although, other people that ski park more than i do and beat them up on rails may have a better review as far as durability.
