New Type IV flywheel options, AA Products unit okay? Options

After the 15% discount which I should qualify for, it would be about $150 before shipping and taxes.

I'm pretty sure my current flywheel cannot be turned down anymore.

Forging is a much more expensive process. I can understand why factory would use it from a product liability standpoint (also may use same forging for higher HP applications?).
Depending on the alloy and impurities in the metal I could see how a cast part could become a grenade if quality was poor. However, if a hardening process was used on a high quality casting, at least for a low HP application it may be appropriate? Because if it's aftermarket, I'd bet it's not forged due to the cost (and what you paid).

What are your thoughts?

Does anyone sell a cast flywheel? I would think the forging process would be less expensive than x-raying each flywheel. The liability seems too great for even an aftermarket vendor to not either do serious QC or forge. It's not like you're going to stop a broken flywheel from coming through the bellhousing. Kind of like a disc in a turbine engine, but not quite as dangerous due to the 10x reduction in rotation speed.
