It seems everyone is mostly recommending Unibiker or Flatland radiator guards. The Woodsblasters look more heavy duty to me (thicker aluminum). Is there something in their design that makes them less effective than Unibiker or Flatland or is it that Woodsblasters aren't polished, the cost, ease of installation? Any insight into why Unibiker or Flatland and why not Woodsblaster would be appreciated. Thanks.
