DT 2.0/1.5mm Revolution. Lubricate the threads with grease or anti-seize to limit windup, and put a tape flag on the first spoke (front) or two (rear) following the valve hole to monitor windup as the build progresses so you can compensate.

The DTs have a smooth transition between thick and thin sections which looks better than the abrupt transition on Sapin/Wheelsmith spokes.

Most boutique wheels not made with proprietary parts now use 2.0/1.5mm spokes, although they've been flattened into a more aero shape which adds $2 a spoke in small quantities.
