I would love to see the WT peloton climbing up the Alto da Torre, after so many years.Alto da Torre would be great fun, and finally give us a chance to test the wattages against the Portuguese machines. If no Angliru, Fancuayu would be best after Cobertoria east, San Lorenzo east and La Colledoria west imo. If there is Angliru we'd already have been real close to there and possibly even used Cobertoria West heading into Angliru so it would be too repetitious and they might need something more like that 39x28 stage that goes over Bustellán (a climb that is ripe for discovery, if they can chain that with Peñas del Viento and then head toward La Colledoria or San Lorenzo west/Marabio south that would be a worthy queen stage). A stage around Granada screams Hazallanas to me, although Hazallanas with a descent finish (or descending through Monachil to climb to Cumbres Verdes) would perhaps be best of all as a final mountain stage.
I've always been a bit surprised Guillén hasn't gone to Atarfe to climb to Los Tres Juanes when he's around Granada too.
