I am fitting W&N lines at the moment, and never having done brakelines before, I find them quite easy to handle. larrges curves by hand. Use a guide for the inner radius when doing radii smaller than ~5 cm / 2 inch. Wrench sockets work as anvil, but there are also cheap 10 euro/ dollar tools for it. I got one of those; work well enough for tight bends. Harbor freight has them in the US.
Have no experience on the rust resistance of the W&N pipes.
Downside of the package from W&N is that they come precut and with fittings, but unlabelled; which goes where is the tricky bit.
Some of them are almost the same length. Measure carefully which of the ~12 W&N pipes you need to select to reproduce the pipe you want.
