I think Gerro held the record for climbing Mt Buller for a while, he can do short hard climbs OK, but you just rarely see it because he is hiding in peleton saving himself.
Here is video of Lama going up paracombe yesterday with live data. Confirms what I said when I drove it 2 years ago - that first 300-500m is much harder than the rest of it, plus it kicks a bit at the end after the KOM point. Last time riders who attacked and chased at the bottom (Porte, Cadel) couldn't go on with it, but Dennis who was dropped from bunch at the base was able to ride through everyone in 2nd half of climb and take the stage win and go on to win GC.
Morton and Chaves are 2 who could ride off the front and stay away. I don't think the climb suits Porte as it is too steep at the start, and too fast at the top - but he can't afford to give a time gap or bonus seconds to any of GC riders. Orica will probably keep pace high in leadup to stop a big break getting all the time bonuses. If Dennis can beat Porte, Evans and Pozzovivo up this climb then Gerro can as well. Will be very interesting to see how it plays out.
