I have a Nallo 3 that I've used on several Alaska sheep and goat hunts. I really like the extra room! My brother in law and I split up the poles, tent, fly etc so it helps on weight and bulk. It's been a life-saver having a large vestibule for cooking and drying gear. It's also nice having an oversized vestibule for backpack, gear, boots, rifle, etc. Several of the trips I've been on have been miserable and a small tent with a small vestibule can be tough on extended trips! We usually use a basecamp that we return to every day. We sometimes bring along bivy bags in case we want to spend the night on the hill.
The Anjan is similar to the Nallo but the fly doesn't come quite to the ground and the materials aren't quite a thick and sturdy. Having a higher fly will allow better ventilation, however, if it rains or snows you may wish you had a longer fly.
With that said, I would highly recommend Hilleberg tents! They are bomberproof! The wind can howl and you can usually expect rain and possibly snow on sheep hunts. I would highly recommend a tent with a large vestibule!

Forgot to mention that another option I really like about the Nallo is it's possible to use the fly plus poles alone on early season hunts. No need to pack the inner tent when conditions are nice! The fly, poles, and painters plastic floor only weigh just over 2 lbs. I've used the fly by itself on several sheep, mtn goat, and elk hunts in Colo, Wyo, and Alaska and it's worked fantastic! We often bring 2 tents to Alaska on sheep or goat hunts. Sometimes we'll leave 1 tent at basecamp and bring the Nallo fly along if we plan on staying out a night or 2.
Believe me, a 4 season fly is pretty rugged...even when used alone! There is gobs of room and it is ultra-light! Anyway, that's an additional use that a lot of guys never consider!
