I'm going to disagree with some of the posters above about the tipi style tents as well. Since I started using them, I think I've slept one night in a standard tent and don't have any urge to go back for hunting season. (Summer with mosquitoes and lots of bugs is when I'd use them - so this will depend on where and when you'll be using....)
Properly designed and pitched - they're fine in very high winds. Kifaru Sawtooth, Supertarp, Paratarp and Seekoutside designs are all great designs. No sag at all and fine in snow for the ones I've used - better than a lot of backpacking tents until you're getting to Hilleberg. Plenty of examples of people using these in extreme conditions.
You also get a lot more space for the same or less weight. You don't have to worry about tracking dirt in and taking your boots off every time you go in and out, and I've never had an issue with pad and bag getting wet. I use one of these at 6 ounces and that keeps everything together and doesn't retain moisture, other people just bring a sheet of Tyvek

Also - no issue with wind or water coming in at all unless it's by choice and you pitch it up to allow ventilation (Assuming you're using one that is fully enclosed and not a flat tarp with two open ends). The biggest issues are condensation, and bugs in warmer weather. But - you can also use a titanium wood stove...
Here's an example. A Supertarp is 2lb 4oz without stove, add 5 ounces for an annex to make it fully enclosed, add 1lb 6 oz for a small cylinder stove and you're right around 4lb with a fully enclosed, heated shelter...
This year - I packed in my Sawtooth for 12 days of solo elk hunting in WY. Could stand up. Had room for a small cot and a chair. Love it.
I have a Hilleberg Anjan2 I think I've used all of twice since buying it. I should probably sell that, sell my older marmot, and pick up a Copper Spur UL2 for my one backpacking tent when I need it.
