Im using Nitto M106 Nas bars @lesterama with a 3ttt record 84 stem, it was an absolute faff to get the stem though the tight bends but a lot of swearing and wd40 worked!
I think the nitto m106, soma hwy1, and deda piega have quite similar compact modern shape. The modern shapes have more of an acute bend. The nitto m151 and m109 are compact shaped but less acute and easier to fit through quills I've found.
