I think there are specialist websites for that sort of thing.
Oh, there are… 😈
Back on topic, don’t underestimate the size of the pitch, it is a very long frame, so may still be suitable. The one I have spare was used by my missus – I replaced it with an enduro (same forks) and knocked 5″ off the wheelbase!!
I admit that I am going purely on the numbers. I’m a gnat’s manhood under 6ft and have a personal limit, based on experience, of nothing shorter than 600mm for a cockpit / horizontal top-tube. IIRC the M Pitch is around 585mm and the L is somewhere in the region of 615mm, which should be about perfect with a 50mm stem.
