with your height and weight, you would be better of getting griffons or jesters.
the squires are mainly all plastic and look like more of a low-end park binding for beginners, or someone who mainly does smaller rails and jumps. it doesnt look like they would work well for a more advanced rider or someone hitting bigger features. not to mention the din only goes up to 11 and these bindings would prolly rip out of a pair of longer, fatter, bigger skis.
just be on the safe side and get a higher performance binding
