dont know alot about the harlaut pros but i had a pair of ar6's last year and they were sickkkkkkk. even without the ar50 sidewalls they lasted the whole season with a couple of top frame SCRATCHES and no cracks, i rode hard on those to but i gave them to my bro and there still going today. armada in my eyes makes THE most durable skis out there for the money. If you have a big budget i'd reccomend some k2 rivivals or domains, both are very durable and lightweight.
out of those 2 the ar7's, all around more durable ski in my mind, lightweight to.
