Trekking bars have much room for innovation, in where you place brakes and shifters on them, and in how you align them. I prefer using mine in "riser" position, where the bars angle up from the stem, while others prefer them in the "drop" position, with the bars angled down from the stem. Some folks like them angled near horizontal, while others have them vertical, and some like the open end facing in (like me) while others have the open end facing out.

Just play around with them, to find a setup that feels most comfortable to you, and tweak at it over time and with longer trips, or change it completely on a long trip, till you have it just the way you want. That means carrying around the allen wrench and screwdriver everywhere you go for a while, as you go through the "ride, stop, adjust bars, adjust brake levers and shifters, ride, repeat" routine.
