I feel it's going to be brass & red James. I (personally) don't care for brass & red in "most" configurations, rather preferring brass & black, with few exceptions. Brass & black lends itself to like coloring with a large selection of woods, where a red spacer has to match "just right" to a wood. If a wood has a red hue, it many times contains dark matrix, spalting, etc. that the black spacer compliments. The red spacer is not as complimentary..."IN MY OPINION"..."BUT"...ya'll should know by now that I don't care what we build!
I have a couple of good customers (some frequent this forum) that "just, plain, prefer brass (or aluminum) and red spacers. Fine. I order what they want. I don't agree many times but they're the boss.
Debate shall persist, I am sure but we'll see where it goes??
Best, Capt. Chris
