Awesome load bars. These look way more sturdy to me than the square bars. They are very stout, and have handled everything I have put on my roof rack so far. They are very quiet, which is nice for those long car rides. Cool, sleek shape. Very happy with this purchase. If you are struggling to figure out which length you need, you can use thule's fit guide on their website, and they will tell you exactly what length you should get for your specific car model.
