What Bindings to Get-

I would go with either the Cypher or the Cartel if you want something on the stiffer side of things. Cartels are a classic binding that have a proven track record of performance so they are a pretty safe bet. The Cyphers are really nice; light as heck, durable, comfortable and made for ripping fast and hard. here is all the info on them that you are looking for on the Cyphers:

Baseplates:
The Slasher baseplate’s lightweight design shaves 100g (per pair) from the Cypher bindings. Polycarbonate material allows for an even freestyle flex.

IMS: Salomon’s patented trick for keeping your disc screws in place while adjusting your bindings or swapping out boards.
Composite 30% Compo-Lite baseplate tech: more rigid than low end plastic, more durable and comfortable than aluminum
ADJ Toe Ramp: dual layer toe pad with super easy adjustability for the best transmission on toe edge
Power Heel Lock: simple heel tab on the back of the heel cup that matches up with the spine on your Salomon boots eliminating heel lift

Straps:
Hollowed out for a lightweight, formed fit, the 3D Supreme Light ankle strap supplies a whole new level of riding comfort. It is padded out for a maximized cushy feel and has a torsional flex for support with no pressure points.
True Grip toe strap is a super lightweight, locking toe strap with no need for a full release to quickly lock you back in - no more cranking in and out of your bindings all day. This is paired with Salomon’s unique and exclusive Fast Fit, the fastest toe strap entry design on the market. Spend less time strapping in and more time riding.

Highbacks:
Flex Rating - 4 (1 Soft - 5 Stiff)
The Salomon Cypher Snowboard Bindings feature the Carbon Drumframe highback with bomb proof carbon construction in an asymmetrical shape and flex, for increased lateral support and better medial mobility.
