Are you looking at the 4 person BA Copper Spur, or smaller Spur (3 person/2 person)? And, do you have any interest in running a stove at some point?
I own an Absaroka with a full insert, and a friend has the 2 person Copper Spur. They're both great tents, but very different in their own ways. I prefer the extra head room, space, and flexibility of the Absaroka.
We rarely use the Copper Spur at this point. It was a great tent that got us started backpack hunting. The freestanding nature of it made it nice if the ground was extremely rocky, and being a 2 person made finding a site a little easier. However, we were crammed in there and would recommend going to at least a 3 person for more space. Which then negates the smaller size of the tent.
I will say, the Copper Spur has stayed in our friends gear closet since our group has acquired an Absaroka, Rincon, SO Guardian, and soon to be a couple Lemhis. We also tend to prefer to tarp/bivy if weather and bugs aren't an issue. Otherwise, we carry the full inserts for those tents.
