Try ditching the 50/34 up front for a 52/36 and then put an 11/28 cassette on the rear.....this "mid compact" gearing has proven to be the holy grail for me. Lose almost nothin on top compared to a standard 53 for haulin ass in the flats or descents and give up only two teeth on the bottom. With the 11/28 out back, you will find the perfect gear ratio to get to the top quick!
