I'm not surprised  Andy's and my answers were similar.
I thought of S-7, but dismissed it because if you don't treat it properly,
it may shatter ( too brittle).
Flat w/ a little crown( edge relief) would be my choice.
I agree that other profiles should be sleeved and adapted instead of
the main die.
