Back from doing the route. Here is what I have learned:
Some of the bolts are loose, so take a spare spanner/shifting or something and there are some seriously long lead-outs. For the rest its fine, but watch out for the weather, we had rain, hael, mist plus thunder.....not cool!!
DO NOT RAPPEL THIS ROUTE!!!!!! Its insaine!!!
Rope drag is very bad whilst pulling the rope thru the chains (at one stage all three of us had to hang on the rope to pull it) and there might even be the possibillity of you not being able to pull down the rope because you are too tired! Believe me, its bad!
Then another problem whilst rapping down is that the chains on some pitches go down diagonally (specifically reffering to the chains bolted on top of the pillar), so you may be faced with the situation where you hang 130m in the air and you have to jummar back to the previouis chains, because the chains where you are supposed to be are 15m to you right. This happened to me, as well as another friend of mine.
Rather climb the route and walk down. Its much safer and a lot quicker.
