But me, while I bring both my Hilleberg or Tarptent, depending on conditions, I've always brought that hammock. I don't do "ultra-light". I tend towards "ultra-comfy".
Obviously there are several ways to look at this, but for me...
The whole point of ultralight to be ultra comfy. Two places where comfort is key on tour are on the bike and when sleeping. The large majority of my time on tour is riding or sleeping. The remainder of time I am still doing things that don't require much/any extra gear. To me there is nothing comfy about carrying a lot of extra stuff.
On the bike, carrying less and riding a more sporty bike is much more comfortable than riding a heavier bike with more gear, in my opinion at least. While actually riding, the ultimate in comfort is a carbon fiber road bike completely unladen.
I don't spend much time in my tent or bivy other than sleeping. A bunch of sprawling space isn't required for sleeping or even for reading.
Combining those two sets of requirements, to me means carrying my U/L backpacking gear. So for full cooking and camping gear I could get by with 9-10 pounds of gear including bags, but I tend to take a little extra and wind up with closer to 14-15 pounds. I don't that so much to go faster or farther, but to be comfortable.
An unladed bike is a joy to ride.
