I went to a Dirt Drop style stem and Nitto Noodles on my Trek 620. I'm not so much of a fan of the look of the stem, and the bars seem much wider than 44.

If I were to do it again (or when I decide to re-do it) I will try the Technomic stem, and approximate the reach. What did kind of scare me is that I had a taller Dirt Drop- and it wouldn't go low enough.

Whatever stem you get- make sure it's not too tall to effectively lower.

As much as I like the positivity of upright bars, upright brake levers and especially thumbshifters... The multitude of hand positions on drop bars is invaluable to me.
