Today I was running late so I pushed it in order to not be too late for work, did the same on the way home. I was so happy to get out of there, I couldn't wait to open a cold one when I arrived. This Sunday I'm supposed to go for a ride with a friend who just bought a carbon fiber bike, should be fun. I have been thinking of buying a road bike myself but I'm not sure I care how heavy it is. My LHT is steel and it is very comfortable to ride, the only thing I'd change is the gearing. I'm seriously considering a road bike built around a steel frame. Seems to me I could keep it very light by spending my money on good components and thus keep it relatively light. I'm in the research phase right now, learning all about what makes a good road bike.
I hear you about steel, I like how it rides too, but I think the cheapest way to save weight on a bike is in the frame. An aluminium or carbon frame will drop 2-6 lbs off steel; a good gruppo will drop 300 grams off a mid-range one. A steel roadbike will never be as light as your friend's carbon job (though it will be cooler and may be more comfortable).
If you don't care how heavy your LHT is, then stick with the LHT.
