About to start brake upgrade project

[767Jockey]

I'm about to start a brake upgrade project on my Contemporary Jag based front end. I had adapters made by Mickmate to adapt Wilwood calipers to replace the poor performing Jag front brake calipers. Do any of you internet wizzes know how to search the web properly to find the best price on a pair of Wilwood Dynalite WIL120-4993 Billet Dynalite calipers? What pads do you guys recommend I use on these? It'll be the stock non vented Jag series I rotors.

Also, I'll be replacing all of my brake lines. Do I use steel or stainless lines? I've heard that stainless is much tougher to flare - is that true? What diameter line do I need, and do I single or double flare? The whole system, including masters will be all new with the exception of the rear Series II Jag calipers, so the lines and flare type will eventually have to mate up to those calipers, whatever size line and type of flare they use. Can anyone recommend a reasonably priced but well made flaring tool that works well? I'd rather spend a bit more on a tool that makes the job better and easier than struggle with a cheap tool It's been many many years since I flared and ran brake lines, so any advice in addition to the above questions is more than welcome.
