Best Access to Steep Standing Seam Roof

We are looking at a project that will require installation of standing seam metal on a 12/12.  Any suggestions on best way to access areas that are not walkable?  Chicken Ladders?  Billy Goats?  Seam grabbers like S-5 type products? Other?

Are you talking about access on metal roofing that cannot be stood on or are you simply referring to the pitch? If the material cannot be walked on then have you considered a man lift?
