Gear for the top two pitches is lots of #3.5 friends (read #3 camalots, blue). HB would say three is enough, I'd recommend 6 plus the odd #8&9 hex. Doubles of everything else. One #4 camalot is enough. Top traverses out left from crack on ancient rusty bolts then a short unprotected crank up a wall to the walk off ledge)
Silent echo is the way to go, it's awesome and justifies the 5 stars in my view. bring doubles from aliens. It is a bit goey and someone did break a hold then their ankle at the start.
Crux is thin hands crank around a roof (first 5 metres off the shale ledge) sometimes seeping.
I hate to give the gold beta out but old fatmen who want to get the crux climb with out the full rack till a stem rest at 8 metres (#1 & 2 camalot fit here) allows the rest of the rack to be pulled up.
