What is this mythical beast you speak of..... a tent without pegs..
It can blow a gale in NZ and BC, but I imagine that the camp sites on the routeburn would have some sort of shelter.
But light weight is usually a trade off in stability. So I guess you need to make the call whether you want to go lightweight and risk having
things go 'south' in the middle of a storm with the girlfriend.
I know which is the safer option..
Picking a tent - well there are hundreds of choices and opinions..
Personally - I wouldn't go near Kathmandu.
I had a kathmandu tent from about ten years ago, it was a great tent. But I think their gear is massively over priced for what it is.
But good tents aren't cheap.
If I had to pick a brand I'd say Hilleberg is worth doing some further investigation.
