My friend has thalls and I have ar7's, which are just slightly stiffer thalls, and there great for the park and all mountain. As well as new york's conditions. There also pretty durable so I'd say get em.
You're pretty much comparing a civic to a corvette, thalls are the obvious answer. Much better quality, and the salomons have been known to have terrible durability. I've never had more fun on another ski than my thalls.
