Not sure how to review a roof rack bar but these are great. I have had every length of these made on all sorts of vehicles. They have held bikes, kayaks, mattresses, mother in laws and everything else in between.
Sorry to hear you are having such a tough time finding a discounted price on helmets. We often times have sales on HucknRoll but you will find the best deals at Departmentofgoods.com. The reason that the odd sizes/colors are so cheap is because they are exactly that, odd. Feel free to give us a call and we can see what we can do to get you helmeted.
