I've used the 0 block up front running rubber/carpet. It made the corner feel two-stage and non-linear. Car would have this initial dartyness going in then would understeer throughout the corner. Really difficult to drive. The added arm sweep of the 1.5 block smoothed out response throughout the entire corner. On asphalt all I run is the 2.5 up front.

An added benefit of more arm sweep is less chatter. The increased angle of the arm actually decreases the angle on the CVD while cornering.
