As for fluid. Redline Heavy Shock proof is the ONLY fluid I would run in a gear box subjected to forces beyond its ratings. I had a STOCK 5 speed last for over 2 seasons of AutoX / Pro Solo launches at significant power levels and very sticky tires using nothing more than that fluid.
The same set up with regular fluids would only last a couple of events, at most, before going boom.

Amsoil Severe Gear 250 is supposed to be even better than Redline Shockproof. It's also thick as wet concrete, so you can expect it sucks up some more torque. Anecdotal evidence quoted here:
Amsoil Severe Gear SAE 250, Medicine for Weak Transmissions
says that it will keep a 1 weekend transmission alive for an entire season.
There are several other weights now, but I don't know of any reliability data on the lighter weights relative to 250.

Broke seven 5 speeds and four 6 speeds and counting. Stacking them up like cord wood.

Makes sense to me. I tried Shockproof in my diff and I've never seen a fluid break down so quickly and so massively. Nothing Redline makes has decent heat tolerance, in my experience (based on uoa results). I could see it working in an autocross car that doesn't get the gearbox hot, but not doing jack **** in a road race car that essentially overheats the gearbox every session.

I did just order some Amsoil severe gear SAE250 to try. Maybe it will do something.

Seems like the focus of that oil was how it behaved with syncros not so much about low friction or extreme contact pressure.
