I use a Haglofs Genius 3/4, the biggest tent off the Genius series, darn heavy (4 kg) but so well equiped for bad wheater.
Up to 12 storm lines,snowflaps, 4 bows instead of the usual 2, a super logic way to set up the tent and the possibility to set up the outer tent first and then the inner tent.

You can choose for the lighter ones like the 2/0 or 2/3
I also like Mtn harwear like Ivana said, i think they make execellent outdoor gear and they really have a smarthinking about their products.
