From memory there’s a face on that block with an obvious right to left traverse (starting at the right arete, finishing by rocking up round the left arete). This is problem 15 on Javu and goes at about V4.
The right arete itself is really good and is about V3 if you top it out.
Lowla starts further right again, on the face around right of the arete. You traverse leftwards along a thin seam, make awkward moves onto/round the arete, climb up the arete then (instead of topping out) link into and finish along problem 15.
None of the moves are desperate, but it’s quite tough linking it all.
