In reply to snoop6060:
I did Mosquitos, Chinatown, Zulu, Fiesta in that order, and it seemed a good progression in terms of difficulty/effort. At that time China town was the best/friendliest equipped of the four. Fiesta had had only the belay bolts replaced - all the gear in between was old - bits of tat, old bolts etc, but the gear on Chinatown was brand new. However, I remember that one pitch of Mosquitos where the exposure suddenly hits was equally spooky as anything on any of the others!
