Given the two choices I'd go with the vivivente just on the lowering gearing alone. I also like the dynohub on the vivi since I bought the same hub for my commuter, I wouldn't want to go back to battery lights. I don't run disc brakes on my touring/commuter and I ride in the snow and rain a lot. I'm a bar-con user but that's because I am cheap, I think any new STI would last for a while.
