I also test sieved on the rational side, that's slightly slower.

It could have been done as a GNFS job, but poly selection would probably take longer than it would save on sieving.

I'll do the LA.

That poly is pretty bad, about 20% worse than the record score for that size and the skew is rather large. Can I improve the poly overnight and post a new job request for it tomorrow?
