Idefix traverses right from the belay of F&EE and then goes up diagonally right to join VH. You can climb direct from the belay of F&EE for a few moves on old bolts, but the holds soon run out. Lots of things were speculatively bolted back in't day (Overshadow, Magnetic Fields extension) but were never climbed. I don't know of anything coming out right from the belay of CA, did the bolts look new?
