I just went through this. I used to ride off road and my Kona Kula 14" was perfect but then I started riding on the road with slick tires, and I could really feel every bump with my Kula. I wanted to find a bike for the right purpose. I went with steel. My LHT fits me very well and is a much better ride. I'm sure you can find a steel bike with STI shifters that will work for you. Good Luck with your search!
