People bitch and moan all the time about how mounting forward of recommended ruins your skis ability to ski all mtn. Don't believe them that is an old school train of thought. I ski center mounts all mtn. all the time. They are super balanced and as long as you have a decent length, very stable. And, I can carve fine. Center mount just really makes the skis feel more natural to me especially spinning and riding switch, you get a better flex in the tail because you have more length back there to press on. Seriously, traditional mounts blow ass, it's all about progressive mounts, it makes skiing way more fun.
ARV's are a sick all around ski, one of the best I have ever owned. I think I had mine mounted a few cm's forward of recommended, but ultimately I wished I had mounted them 1-3 back from center. I used them as an all mtn ski that still slayed park, and they would have been sick and very versatile with a near center mount.
