Just a thought, have you looked at a master yarn sett chart like the one handwoven magazine has for free? You could compare the setts for linen to the 8/2. Maybe 16/2, 20/2, 14/2? (Have no clue what they look like).
I have little experience with linen since I’ve been using cotton for samples due to cost but worth looking at the chart? I’ve been eyeballing the chart myself as I summon the courage to try drafts from Vav which often use yarns. Unfamiliar to me.
Vav might even have something on yarn.
You could also ask in a Ravelry forum like warped weavers or email Glimakra ? The one in the US is probably bilingual in Yarn Speak/numbers.
