They are right about how hard it is to do it yourself. First off , you need a double flaring tool, and some practice. Personally I've never had any luck doing it, and always order custom made pieces from one of the companies specializing in this work. The cost is surprisingly low, and I always buy stainless tubing. It has been on my one car for many years, and looks like the day I put it on, and it won't rust out, ever.

An area that I may get some disagreement on is that I love silicone brake fluid (dot 5). I've heard all the stories about spongy pedal and the like, and have had the same fluid in my '27 for 15 years, both on the brakes and on the hydraulic clutch. I can get in it right now and the brakes are perfect, after sitting for the past 5 years. I like it because it won't eat my paint, and also because it doesn't suck up moisture like regular fluid.

It's just my opinion, but I will never use anything else.
