Invaders are stable no matter what anyone else says. At high speeds they work fine, they can pull you through tight spots near death that I didnt think possible, even switch. It's just a bit loose in the tips, so if you land way backseat it tends to slide out (which can be quite fun riding in a manual doing turns) and the cosmetic delam gets on your nerves since most people get it. It's nothing to worry about, just EPoxy it or whatever. All around though, the most hated ski this season might be one of the best.
