Rab alpine bivy or OR helium bivy

I need to get a bivy fot a summer mountaineering trip. I am looking for light as possible. Both of these are around 18oz. I have no experience with bivys. I would think the Rab would be a little more breathable being 3 layer event. However, it does not have a pole to keep the bivy off your face. Is this not a big deal or is it worth getting a bivy with a pole to keep it off your face? Also, the alpine bivy has no bug netting. I have read the OR bivy has a few issues with condensation, but if you vent the opening around 5 inches it helps. It seems that no matter what the material all bivys seem to have condensation issues. Anyway, any feedback would be great.

Look at the Black Diamond Twilight bivy. I have one and it only weighs 10 oz.

How does it do in the rain not being waterproof?

Yeah, condensation is always an issue. I've even known someone who died on a clear night sealed up in a bivy some time ago testing it. So be careful out there.

Bug netting is real nice if you are "needing it". Poles are really a judgement call depending on how you sleep with stuff in your grille...

My current bivy is an older Bibler, works okay and has some good features like full strength sling integrated for big walling. The bug netting is wonky though and let's in plenty of buggers..
