so everybody trying this route is probably aware of the loose block..... anyways ive done it a bunch of times over the last 10 years & had another lap on it yesterday.- I reckon its getting prettly close to falling off (I'm talking about the block after the proper crux - not the glued up flake on the cheat variant).. The whole thing moves quite a lot more now than it ever used to (or maybe im just getting fatter). So just a warning to take care on this one, make sure your belayer is as out of the way as possible and tread lightly!
