OK, so this past Thursday, I picked up a Univega Activa Trail to be my primary commuter. The setup so far is with cantilever brakes and rapid-fire (drop) shifters on a riser bar (horizontally flat).

Now, I don't want to throw drop bars on this bike, as I like the upright ride for a commuter, but my hands start tingling after about 7 miles (I've got a 20 mile RT commute).

I'd like to switch handlebars, and have been seriously looking at getting a set of mustache bars (with road levers and bar end shifters), simply so I can still sit up while having multiple hand positions, but are there any other bars that would help me out as well?

I've looked at multiple bars that are out there that are more "ergo" and swept back, but I don't know if any of them would work well. The others I've noticed are the:

On One Mary
Nashbar Trekking bar
VO Milan
VO Left-Bank
NITTO Dove
NITTO Albatross

I'm seriously considering a cromoly albatross if I don't get the mustache.

As an aside, either way I go (bar-ends or retain the MTB-style shifters), it's getting friction shifters, so changing things isn't a big deal to me.
