I have a 9 speed Tiagra triple on my Jamis Aurora (2009) and 10 speed Ultegra Compact Double on my Roubaix (2012). I hate the 50/34 chainring combination. Can't get in the right gear. The middle ring on my Jamis is a 42 and is perfect. I am guessing, I would be a lot happier with the cyclocross 46/36 combo (as suggested by Jiggle above). If I need to, I can always put the 12-30 cassette in the back.
