In reply to AntonY:
I think it depends on how cold your hands get.
I had really cold hands on Kili and was glad to have a pair of Rab Mitts (the old ones, this is 15 years ago) in the rucksack. It's the only time I can remember having cold hands on a mountain and I've been a lot higher than Kili.
Gondogoro, I've not done but have been very close to it on the Baltoro at a similar altitude and it was never that cold early morning in summer. You will set off early on this.
If you can afford them (and I assume you can because you can afford the trip) I'd go for the Altis. I would love a pair, but there's still nothing wrong with my old Rab ones apart from being very bulky so I can't justify owning another pair.
