Hilly area pram suggestions

[Lemoonada]

I bought my current pram when we lived in a very flat city. We have the uppababy vista which is very slick but extremely heavy. We've recently moved to the countryside and it's so hilly. I'm also pregnant with baby 2 and wondering what on earth I should be using as a pram when baby is born. I'll need a double but wondering what could possibly fit the bill. I've even considered the cybex electric pram but they don't come in doubles.

For context I have a travel pram that is reasonable to push, 7kg on its own and DS is currently 12kg. Uppababy is something like 14kg

Any suggestions very welcome!

I used a Mountain Buggy Duet, it was easy to push even over rough ground and a brake on the handlebar made it easy to slow the buggy down on steep slopes, it also fits through narrow shop doorways.

BJCM, had twins, changed from the bugaboo donkey. Couldn't fault it.

I had a Mountain Buggy Duet. I loved that pram so much. It can cope with anything and fit through my narrow gate.

Mountain buggy duet 100% I was a childminder for nearly 40 years.
100% this is definitely the best double buggy on the market

The mountain buggy duet was the one I was tempted by but is it heavy and hard to push up hills?

I live somewhere with a lot of hills and it was easier to push up hills than my very light bugaboo bee. Even though it’s heavy it has good air filled wheels and good steering. But it is heavy for eg lifting in and out of cars.

And does anyone know why the luxury mountain buggy is any different? It just looks heavier for no apparently reason? And much more expensive
