I've started moving away from the teflon lines, which is what is inside those steel braided flex hoses.
The ends break too easily, the nylon can fail without any visual warnings.
On my wife's TJ, when I get a chance it'll be short rubber lines with steel line running down an upper control arm.
On my YJ, not sure how I'm going about that yet, but the extra long lines keep getting nailed between the bump stop and axle no matter what I tried. Just hasn't been an issue with it parked the last 5 years.
