I'd guess (standard very non expert disclaimer!
) that it would be the Electronic Brake Force Distribution (EBD) that would control the brake bias behaviour rather than the ABS. I think once the ABS is cutting on on the rears the rear will be twitchy, since you have no additional cornering grip available - the braking is taking any additional grip available.
I would think that the EBD should be able to prevent getting to this scenario of ABS locking the rears before the front.
I'm pretty sure that having different pads front and back isn't normally a good idea for any brand of pad since you want the same temperature/perfromance curve for both front and back, exactly as you describe.
I have the GT 3.2 V6 callipers on my GTA, the callipers look bigger than AlfaDublins ones so I am not sure if the GT 3.2 ones are the same as the upgraded GTAs ones, or AlfaDublins ones are just another variant.
I have only done a few track days with the newer brakes but my initial impression is that its slightly harder to bring the tail out intentionally under trailbraking, but have admirable stability.
At the moment I'm happy to keep the rears standard while I experiment with using left foot braking to create additional rear brake bias as needed.
My thinking about having my current "safe" slightly front biased setup is that if I overdo the left foot braking too much that just relaxing the throttle will cause the bias to move forward which will stabilize the car.
Now - why didn't they teach us this stuff at school!

Under normal driving conditions, the car feels well balanced, but, as the brakes heat up, the Ferodo works better and better compared to the Red Dot pads, and as a result it becomes twitchy. Untill i get my Ferodo pads for the front, my car is actually very limited on the track.. Amazing how big a difference a set of pads can do!
So like you say Trailbraker.. you really need to think about how you set up the distribution front to rear!
