Some advice from the anchor gurus out there please.
So a long multipitch slab, each belay stance protected by two bolts. How would you rig the belay whilst the leader is leading? The two main questions being is there anything you can do about protecting an upward (kind of horizontal as well on a slab) pull and in general at such belays would you belay directly off the harness with a redirect or reverso 3 style directly off an anchor and, if so, would your reverso be ABOVE the anchors to protect against said upward pull.
Hope that makes sense, any help appreciated.
