I like the looks and the feel of the "drop" position, as irclean describes it. I thought about mounting them the same as irclean has them, but I wanted a lower, slightly more aggressive riding position. I feel more stretched out and more horizontal (i.e., less upright) on the "upside down" trekking bars.

I don't have extensive experience riding on drop bars, but I agree with IanHelgesen. From my drop bar experience (which is even more limited than my one week of riding in trekking bars), I'd also say that when I have my hands on the sides or the top (front) corners, I feel like I would if I were on the hoods of drop bars. It's a very comfortable riding position, and I've noticed this week it seems to help a bit of when dealing with a headwind, which is to be expected, I suppose.
