We needed and alternative to our 2005, 75 ounce, MSR Hubba Hubba.
The Fly Creek 3 is a contender.

Here is the inside with a 72" Thermarest and a 72" KookaBay.
This tent is not staked to our floor(couldn't find a big rock). So dimensions are a little short, but probably pretty close to what would happen in the field.
I measured –
83" front to back
59" near the front, at the pads, 9" back from the door
34" in height where I naturally sat up
42.5" maximum height
Weights –
Body….18.87
Fly…..16.96
Poles…14.95
Stakes…5.02, (there are 13 provided, and they look quite adequate)
Repair Splint — 0.40
Tent Stuff Sack – 0.80
Pole Stuff Sack – 0.38
Stake Stuff Sack- 0.17
Total: 57.55 ounces
Weight could be reduced a little by removing the plastic clippies on the fly lines, cutting off some labeling, and leaving the splint behind. But I doubt if you'd get below 56 ounces.
The ends are nearly vertical, as are the sides, so utilization is very good –

There is a lot of volume in this tent. We can sit up side-by-side, without getting an elbow in the ribs. And with all the netting, no sense of claustrophobia, unlike the FC2, which felt very restrictive.
Looking at the ends shot, note the triangular pockets top and bottom. Even though the vestibule is a little small [edit: Not- see below], it will hold packs and boots, with the rest of our stuff tucked to the sides and in the pockets.
