^^ I think it would just crush the core. Lol.

But the worrying part about Bowing is that once Bowed, you cant go back to Flat.
I still dont understand why though? Wouldnt it just be that the Copper is somewhat "Flexing" outwards, and non bowed, it would just flatten back. I guess im just a noob though. Lol..

I still would prefer Lapped IHS + Lapped HS.
