Not quite "Roval style". I hadn't even imagined this odd, 3X way!
On my 24-spoke Roval rear wheels, there's 2 crossed DS spokes for every (radial) NDS spoke. There's no extra "holes" (tapered slots, actually) in the flanges for the straight, T-head spokes and their rim's 24 spoke holes are all equally spaced. Whether Jerry's 30-hole rear hub would have to be laced either way, "Roval" or "Zeus", would depend on whether the hub drilling is 15-15 or 10L-20R.
Roval's advantage was more-equal spoke tensions left-to-right, and remember these remained in production into the 8-speed era when dish became yet more severe. They even addressed the axle bending/breakage issue (as did Maillard and Shimano in their own ways) with a special, extra-fine, extra-shallow threading on their 10mm rear axle.
Roval's biggest faults are hidden (by the tire) nipple hexes and the thick, nylon washers under the nipple heads, causing tension loss over time (why I got mine so cheap!). As special-event or pro wheels, neither problem precluded their practicality, but as occasional-use wall-hangers or seasonal warriors it can present an occasional hassle. Thankfully I have yet to have a nylon washer ever split, but will they last forever?
