Which orientation will have lowest toughness?
Which orientation will have lowest toughness?
(OP)
I am dealing with hot forged bar, about 6" OD.
It happens to be 15-5PH, but this should apply to any age hardened alloy.
Which position/orientation will have the lowest impact toughness?
I can think of nine different combination to take impact bars, but I only want to take two.
Which will give me worst case?
Opinions are welcomed, if you have a good reason.

I know that I want the notch running in what was originally the L direction of the bar.

Look at the figures A5.1 and A5.2b in ASTM E23. The T-L in A5.1 is also called Y-X, which is a tangential specimen with a radial notch. I doubt there would be much difference between this and the Z-Y orientation (S-T) in a round bar, but I think the conventional thinking has the T-L being the lowest for round bar, RCS, plate, or slab.
