Brake line selection - what size, material, etc..

[Asshat]

Looking for a good explanation and recommendation for running brake lines. Planning the cross member swap; I’ll have discs up front (from a 74 C20) and rear drums (from an 83 C20).

Really just concerned with running the front lines, properly flaring the tubing and using the correct fittings and tees. I believe steel is the easiest to work with; I figure I’ll probably need no more than a 25’ roll.

Also, 1/4” ok to use for front discs from master cylinder, all the way to the back tee?

Seems like there are so many options out there. Any help would be appreciated.
