A box of donuts walked into a heat treat shop and they would take the 5 minutes
to test hardness. It is easy. The hard part is getting a mast to the shop!

It's good to know that it can be tested. It would probably require
"connections" to get this done at a price that wouldn't exceed the value of the
mast.
Can you expand on your comment about the chromoly obsession?
I too keep reading the chromoly "hype" (?) here on TT.
Is it possibly overrated? Or maybe it's the real deal.
I don't have an opinion as a non-expert; just trying to learn about it.
