One thing with the Signal though is that it weighs 32 lbs. My Hoffman was about 37 lbs, and I really hate the weight. It was one of the main reasons that I decided I needed a new bike.
I could get the Signal if I suddenly realize I don't want to get the Metric, but I don't know. The Signal doesn't seem to be quite as much "flatlandish" as the Metric (the frame differences are quite different and all). I would rather spend $500 on a bike that I would really like that $300 on a bike and have a chance that I wouldn't like it (the main thing right now that I don't like about the Signal is that it of course weights a good amount more, and it has an unsealed freecoaster, whereas the Metric has a better sealed one).
But thanks for your opinion! (You are actually the first person to post a reply that is actually on topic in a while, hehe.) If I suddenly find some reviews or something on the Metric and it's a bad bike I'll probably go with the Signal.
