N Side of Timor rock is conglomeraty and crackless. Looks revolting.
Minifig/German Tourist / Neil on the Moon/ Belougeries Pinnacle in the guidebook has the route Sculptor on it also if you like a 17 jam-up. Must have been missing Frog B. Topropoing there would work well but its a bit of a walk.
I wouldn't recommend taking anyone too inexperienced on any of the big routes regardless of the grade, unless accompanied by a capable climber at the other end. If you get into trouble, even something like a rope tangle and you are a long way away up a big face you will have a lot of (non) fun before you get back home.
