I think copper brake pipes are illegal in some countries, not sure on the UK.
I have always used Kunifer.

Normal nipples are just fine, once done bleeding stick some grease in the nipple rubber cap and refit said cap.

I have used cunifer and brass fittings. I then painted the fittings with Lanoguard grease after fitting.

I have also used s/s bleed nipples.

Personally I would avoid copper as it is so soft it can twist when undoing the fittings.

Also, with cunifer, get it from a reputable company. I have read that some of the cheaper stuff is just coated steel. When you get it test it with a magnet - if the magnet is attracted to it then ots steel and will soon start to corrode. And when you shape it, form the tube around something to avoid kinking.

When you take the old pipes off look after them as you will want to copy them.
