In reply to robhorton:

Yes Croix de Toulouse is especially good if you like to make climbing moves with hands and feet directly on the rock (using the steel cable only for protection, not aid).
Aiguillette de Lauzet by via ferrata is supposed to have nice views, but I've heard does not offer much climbing with hands and feet directly on the rock.
I found VF des Vigneaux to be good for direct rock moves, but they don't go to a significant summit.
