Lets get the negative out of the way first. That is Size. I am in a Burton Ion in 9.0. The straps are marked M/L and are shortened most of the way. The Foot Pillow, as they call it just sticks out a bit passed the sidewall when the binding is centered. The size chart says 7.5-10. Unless your boot is very high volume, I am find it pretty unlikely an 8.0 will work in this binding.
That out of the way, this is the best binding I have used in a 22 year snowboarding career that includes being an instructor, ski/board shop manager, and big mountain competitor. I'm 165 lbs.
The description is pretty right on. a freeride binding that is still soft enough for a playful and surfy style. In really serious chop and chunder there is a little more of the ankle wobble than the stiffer bindings (I also have a Mercury), but the gains in suspension with the Progressive Highback make up for it. The strap is a tiny bit softer than Mercury, but I do find it more comfortable.
Overall the feel of the binding is very natural. For those of you who haven't experienced Skate Tech initially doesn't feel as crisp edge to edge because it rolls (much like trucks on a skateboard). Once you are used to it, it honestly feels quicker because instead of jerking from one edge to another every part of the roll comes alive. It also increases the suspension of the binding while increasing the precision. You will see a lot of short term reviews out there saying it is slower, but once you have spent enough time on them to learn the feel, and then go back to another binding, you realize how much you miss by not being on a Skate Tech binding. I have had several weeks on Orion, but have had a Mercury for all season and have ridden NOW bindings for many years, so this is a very long term review of Skate Tech.
As for design in general, There are some negative reviews about setup difficulty, but if you read the manual (GASP! Not the manual! Heresy!) is is actually pretty simple. I do wish they still offered offset plates for those of a big or small size boot who needs 1/4"-1/2" stance width adjustment. The strap adjustment is easy on the fly. Ratchets work very well. The highback forward lean adjustment is easy and works without tools and for a duck footed rider like myself, the pre-rotated highbacks make life easier, although it might not suit the alpine stance crowd as much.
As for the Specific model, all in all, The Orion is the most natural and comfortable binding I have ever ridden. Mercury is a little more powerful and stable, but there is a little more strap and highjack bite. The highback of the Orion feels just as powerful on engagement, but flexes very natural through terrain variations. The ankle strap, likewise has a very natural and comfortable flex in action. If you are upwards of 190 lbs. this may be a bit more on the freestyle end of the spectrum, but at 170 lbs. or less Orion is a spot on all-around and freeride binding.
Now please enjoy these gratuitous pow shots of me on the Orion from Monarch Mountain.
After several weeks and one freeride competition under my belt, I would rate these my all-time favorite binding. If you charge hard and value style and fluidity, this is definitely your top contender.
