I've seen a couple of the 100% rigid line installations, in addition to being a pain to do, there IS a slight amount of flex between the transmission and the body during operation (due to rubber engine mounts) that would tend to weaken the hard tube over time. In reality, this is probably a 10-years-of-normal-driving kind of problem. If you were designing this to last 100 years the best thing would be a hard line with a flexible piece on the transmission end, in practicality the overall braided version is fine.

It is much more resistive to crimping or crushing than a rigid (solid) tube, therefore the braided flexible line is far superior to a rigid line. As a side benefit it is much easier to install than a rigid line. > > > DMC Joe
