I had to use a stem riser to get the bar high enough to "fit" me, and added padded tape over the provided foam bar covering for more cushioning.
The trekking bar positions the shifters and brakes as on a a flat bar. The Safari came with Grip Shifts, but Rapid-Fire type shifters would fit just as well.
My Cannondale handlebar bag fits on the trekking bar.
I can't think of any "cons" to the trekking bar. It's a bit wider than drop bars, gets some "what the heck is that" looks, and would be a challenge to fit a mirror on (I use a helmet mirror).
You could get a trekking bar from Nashbar for $18 and give it a try.
