Do any of you guys use a Saris Bones 2 bike trunk rack for your bikes? I just picked one up for my toyota Corolla. Strong construction and all that, but how tight is the straps supposed to be? Also the side straps don't really have a good angle to secure in the trunk if that makes sense. When the side strap is hooked in its not completely straight with the strap so basically the strap buckle is angled more in contrast to the strapping. I'm worried this will come loose. Maybe I could use some extra foam in there to prevent any movement. Any ideas on this? Nice product but am nervous about going on the highway with this. Help!
