Addict Pro: For kicker and halfpipe pros. The contest model with carbon swingweight
insert in shovel and tail section. Developed by the pro riders for top
results at national and international events.
Addict: For park, pipe and big air. The Slopestyle ski that can do practically
anything. Real Twintip with Sandwich construction for identical
forwards and backwards skiing.

Also I am pretty sure the Pro has a titanium sheet in it and the Addict does not.. somebody correct me if I'm wrong.
I have heard great things about the Addict skis though, I would say go with the Addicts, you don't need the stiffness of the Pro. I choose these over the Suspects because of quality issues, the Suspect is an awesome ski.. just doesn't hold up. Plus Fischer is a respected race brand that happens to make some sweet park skis, so you know the quality is up there.
