I bought a jconcepts hi-flow body from all the rave reviews about how it was so durable. About a month of racing later the entire front end tore off and i had to RE-SHOO GOO the body. I normally don't crash, but a couple of times it landed pretty nasty. Ie; when the truck would nose-down and i can't get it back up, when i parachute and it lands flat on it's back. I'd label the body medium thickness as a opposed to and ftw body being very thick. It might not be because of a few crashes. A friend of mine told me how "bulldog adhesion promoter" can make the body brittle. It kinda of made sense as when my driving improved, my body's lasted the same amount of time. I tell you what though, jconcepts body thickness is like a phone-book compared the the parma bodies.
