Most people seem to agree that the TS is a good option, and most run the carb setup and like the feel of it for "the road"
But what is the road in most peoples case? Is this "their stop and go in traffic to get to work" road, or the "saturday blast around the hills with the radio turned off and window down" road?
May seem a strange question but the charactistics everyone talks about are always aimed at the "fast" side of the road.
what is the best set-up for the everyday side of driving.

It's interesting that you asked this because I've been wondering the same thing. Before I offer an opinion, however, I want to make clear that I do not own a ts and have never driven a car with the ts installed. I have, however, paid attention to older posts (there's a wealth of good information here) and I have PM'd some people who do have experience driving and building both Nord motors and TS motors. Ok, caveats aside, here's what I've concluded.
For now.
The twin spark is basically a Nord motor with an improved head. If you are replacing a carbureted 2L Nord motor with a TS w/Motronic there is, indeed, a marked increase in horsepower, flexability, fuel millage, etc.
However, if like me, you can use/build a modified 2L (in my case, high compression, ported head, big valves, cams, ignition, balanced, etc.) then the difference between the old style Alfa motor and the TS isn't that great. The differences are so small, relatively speaking, that I can't see the utility in going to the trouble to make the change.
In saying this, I am hardly claiming definitive knowledge. In fact, I'd benefit from having the opinions of others with direct experience running both motors.
