edit.. okay, I went through the article. I didn't actually READ the article mind you, I just looked at the pics/ geometry. You want a Cannondale topstone. It gives you the most of what your current bike is not. Raleigh comes in second. DB and Tomasso's come in third. Pure cycles might come in first or last depending on riding you are doing. Single speed comes in last because it it too uncomplex.
