Start up Fingerdrive, move right and climb over bulges direct to the hole on Castor and finish direct (a more direct version of Castor).

I think that the line shown as Castor in the Rockfax guide and on Gary's site is in fact the more direct version of Castor which on UKC is named "Corky Fruited Water Dropwort". If I'm right the original Castor traversed right at the thread and climbed the lesser bulge which is now part of Cronus before moving back and climbing past the nest mentioned on Gary's site. The direct line (whatever it should be called - I'll leave that to others) is certainly not HVS and I reckon would be tough for E2! (I've also put this entry under "Castor")
