Cast vs. Forged Crank?

There's been a few threads recently about scat cranks in the stroker kits, pertaining to balancing. The consensus seems to be that if you are going to internally balance your assembly, you might as well go with the forged crank as by the time you balance a cast crank and add Mallory the price comes out pretty close.

I went with the scat internal balance cast crank stroker kit and my engine builder said it was good to go but another member here had to add Mallory to the crank to get his to balance.
