Can confirm Black Diamond at Tactical 2 also, Crystal needs MV4 only too to get it quickly.
Indeed, Sting-20 is excellent. It finds the key at depth 3 and the line at depth 7. This is with all setting at default (so, in particular, Threads = 1, giving a deterministic search):

Dann, would you mind testing Corchess_V6 ?
It's a very interesting engine because it has a very high rating and it solves a lot of positions.

I will give it a try, but my machine is booked right now doing something for me.
I could run it on another machine, but that would not answer the question.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Yes, I used 32 threads on my 3970x (Arena will not allow me to use all 64 threads).
The machine is pushed to 4 GHz. It has 128 GB RAM. I have full 6 man Nalimov and Syzygy tablebase files on PCIE 4.0 m.2 gumstick SSDs (Really fast and it makes a difference, with an ordinary 1TB thumb drive I was saturating 100% disk access and cutting down NPS to 10% in certain "tablebase mad" positions).
The houdini version tested was 6.03, but not the tactical one, which I am going to test now, along with the "houdidit" version because I am curious to see if the results will be identical.
