Using a (or a couple of, s also described already) grub screw on both sides of the lug might not be a good idea, as the lug has a split at the clamp portion of the lug already that the grub screws might just splay open and the seatpost will loosen up eventually. I think the best solution is the already described bolt-through
compression method.......
Also note that with the grub screw method used by Vitus, the aluminum lug was substantially thickened up at the back of the seat lug, around the grub screw, so they could put in enough threads on the lug to support the grub screw and the lug can take the stresses comig from it without cracking...... I don't think there is that option with the lug on the subject bike.......
