I switched to drop bars on my Trek 1000 (predecessor to the 1.2). I love the drops on windy days, and I could see the clear benefit of drop bars on a 30m rt commute. Also, go with the Jamis Aurora, if that is the bike you want, and it is comfortable get it. It has better brifters on it than the 1.5 (Tiagra v Sora) and it is cheaper. Sora = crap

But really go with what is the most comfortable for you (the Jamis...go with the Jamis)
