Hello! As far as "comfort" on a road bike, I feel that's based on what you're used to. A friend of mine said she had a hard time bike shopping and comparing bikes because she just couldn't get over how *different* a road bike felt compared to a more upright bike, such as a cruiser or mtb. She wasn't comfortable on the road bikes at all and tried to warn me of this before I went shopping. Me on the other hand, I used to ride my ten speed all over the place and was perfectly comfortable on it. The last two years I had ridden a mtb occasionally, but when I started testing road bikes I felt perfectly comfortable on them from the get go. They are built for speed and I like speed . (I'll also mention that my DH did his first triathlon in June and let me tell you I saw all sorts of bikes being used for the 16 mile ride, just about everything except a unicycle!).
