Question about brake set up!

[Apogee]

You're in West Virginia, so the benefit to stainless steel hard lines is corrosion resistance and aesthetics, however my choice would be copper/nickel tubing over either stainless or steel Bundy tubing. You would have to actually work at it to make a bad flare with Cu/Ni tubing, it bends easily without any special tools and it will polish up to a nice sheen if you want it to with a little effort, although it will have a bronze tint to it due to the alloy.

You should abosolutely not be running two proportioning valves in any given circuit...but there's a lot of confusion between combination valves, proportioning valves and distribution blocks, so are you sure yours was a factory disc/drum or disc/disc proportioning valve depending on your application?

A tee in the front circuit and adjustable prop valve is about the simplest you can plumb your brake system, but it is far from the only way to do it.
