Cast vs. Forged Crank?

I am starting to put together a list of pieces for my stroker build. I have decided to go with either a Scat or Ohio Crank assembly but my question is which crank to go with. The goal is around 475 hp on the engine and possibly later down the road a 200 shot. The car will be about 70% street 30% track time so I will be revving this motor quite high a few times a year at least. I had planned to go with a forged crank just for the peace of mind and to know I would not have to go back into it again. Now I am starting to question if it is really necessary. What are your opinions?
Good choice. I run their kit, solid roller, turning up to 7000 rpm...iron crank.
Whatever makes you feel warm n fuzzy inside.
