You guys are all going about this wrong. Rotating weight -- big deal, static weight -- not nearly as big a deal as people make it.
Let me give you some benchmarks:
Carbon Frame - ~2 pounds
Aluminum Frame - ~2.5 pounds
Ti Frame - ~3 pounds
Steel Frame - ~4 pounds
So spending a butt load of money to go from a steel touring bike to a carbon touring bike just to save 2 pounds (everything else being the same) is nonsense.
Now before you flame me and my immediate family, lets talk about some other things.
There are components and architecture (not sure this is the best term), and as someone else said, what kind of riding are you really going to do.
I have a classic steel touring, and the frame weighs 4.5 pounds. She is designed to be ridden from the Canadian Arctic Circle to the tip of to Tierra del Fuego and back, and I can even ride from my home outside Detroit to the starting point too. Everything about the bike is beefy (and heavy). What makes here sluggish to ride are the indestructible rims and Schwalbe Marathon tires. I have never weighed the bike but I put her in around 30 pounds. And I typically tour with a 60 pound kit (some groceries and a nice kitchen).
I also have a carbon fiber gravel bike, and I think she weighs about 23 pounds. I did a bike packing trip last spring, and bike and kit came in at 56 pounds. Handling was superb, and you would never know it was loaded with a kit. The kit was very spartan. If temps got below freezing, I was screwed. I had enough clothing for 3 days, and I used everything except an extra pair of socks. I should have used the socks, but on day 2 it was too cold to change them. I carried no food or cookware, and don't know where I would have put them if I had to carry them.
So please sort out what your needs are, and don't be surprised if that turns into multiple bikes (I have 6 bikes). This is a lot more complicated that steel versus aluminum. Be advised that there are a lot of ill conceived bicycles available for purchase.
