You've gotten some brutally honest feedback and I hope you take it the way it was intended. Brakes are a critical part of the build, so it is worth taking a bit of time to make the system work well and be as neat as possible. The lines that come with the kit are okay, but not a custom fit solution unless you take the extra step to make them fit better by cutting and re-flaring them to fit better. The Nickel-Copper tubing that many use is very easy to work with and not cost-prohibitive if you want to make custom lines for your car. Also, like others have stated, use sealant only on the tapered thread connections. I use Loctite 545 for these.

If you do decide to go with Nickel-Copper, this simple tubing bender is easy to use to get bends that look great without spending a fortune on tools.
