is it worth swapping 10.7 inch discs for the 11.8 inch?

I'm going to take the opposite direction here, and tell you that i swapped over the original disc brakes on the 71 Cuda, that i once owned, to the 11 3/4 inch rotors, back in the day, when the Mopar crowd first started doing this swap.
I never noticed any difference in the braking, wether street driving it for years, after the swap, or hitting the brakes, at the end of the quarter mile, while drag racing it at Sacramento Raceway.
And i used to run 13.20's at 108 MPH, and never had any problems using the first return road, at the end of the run, with the standard brakes, or the 11 3/4 ones.
My 2 cents worth on the topic.
