The application of both the U-Hub and the A/B/C are all to control roll center, and roll center is a setup variable that has more to do with "feel" than anything else. Pretty much all setup characteristics in the car are affected by or will be affected by roll center.

It is very hard to say that one configuration is going to be best for ALL surfaces, and you have to realize, when a SoCal driver says "Low-Grip", many people from the mid-west would call that medium or high grip. Comparing a setup from one end to the spectrum to the other is going to be very difficult.

Rather than discuss which configuration is best, it is best to understand what the changes do, and if the car is not doing what you need, to learn what to do to fix it.

Don't give the man a fish, teach him to fish.
