what's a good way to splice 2 #10 in a trough, Are the Isco lugs with the plastic around them OK, or is Burndys wrapped up in rubber and 33 better?
 
Its #10 your correct a wire nut would do, I mentioned wire nuts to the PE and he said he preferred some sort of lug,

To be honest, for a wire that small I think wire nuts will make a better connection. The other connectors you mentioned are for bigger wires and I never liked putting smaller wires into them. It just seems like they float around too much and the lug pushes them to the side.

I wirenut #6’s together all the time and they see 48 A for a continuous 10+ hours and I’ve never had an issue.

Then use the insulated Polaris type connectors. Easier for you. The only reason why I would go back to old fashion connectors that I had to insulate myself would be to avoid paying the higher fee for the Polaris connectors.
 
Wire nuts for sure. If you use a Polaris it would most likely be a IT-4. Torque to spec then you push them into the enclosure and that torque spec has been compromised by the movement.
 
If they don't want wirenuts then as EV said use a Polaris style connector. Dumb and a waste of money but they're paying. A split-bolt with tape is IMO the worst possible connector type.
