I did Vertigine a few years back. No guide, we took a photo of the topo in the new routes book in the cafe at the base. Took us three days, though it was December and we were hauling portaledges. 8? pitches of HVS slab climbing followed by a lot of A0. Not much point in taking a rack, though a clipstick would be useful if a bolt is missing.
I think you need the Sarca Walls guidebook, it has all the multipitch in the area in it. Being <6b climbers we noted there was very little in that grade range without any aid sections.
I don't have the book handy, but iirc there's some all free stuff at reasonable grades further down towards Arco and further up at Sarche - but yeah, not much on the big central section around Monte Brento
