In reply to d_b:
This is the topo for the climb from the col (fra bandet) and the harder variations.
This climbs directly up the ridge and should be pretty easy to follow a similar line down.
The descent for all of the climbs here is described as by abseil down this route (or back north over the ridge) in the guidebook, so there may will be tat or even nuts/chain anchors (as on the neighbouring Skagastolsryggen).
The guide however offers no info as to where these are.
The pitches are 30-40m so it is likely that the abseils are set up for 50m doubles and follow close to each pitch. I did a quick mooch in Norwegian but only found that its easy to find belays and that descending the route is an option, I guess mostly because people climb it then return over the ridge.
As an alternative you could do Skagastolsryggen and north side of Støren on day one, to a bivvy at bandet, then climb Dyrehaugstind via any of the routes from bandet and go north over the ridge.
