I use my dvorak PBT dyesub set on a backlit board. The keycaps are normal PBT, but look great over LEDs, and the legends are still clear
So it depends on what, exactly, you're after. If it's keycaps designed for back lighting in mind, then it's flat profile / TG3 for you. Otherwise, most Dvorak sets are compatible with backlighting with various degrees of success. I like imsto's best.
