I've had some brilliant hunts up there in Oct-Nov. Ive also been challenged beyond belief and needed all my reserves in the young guy learning what his limits are and then finding new skills and limits kind of way. It can snow out of nowhere and the wind can be hard to stand up and walk. In the days before GPS the fog was a nightmare. The great thing is if you plan it right, you are less than 2 hours in bad conditions from Rangi hut.
Well worth a look along any of the spurs off that main ridge.
Good luck! Its a special place when you get too know it.
