C150 is about where I started to tinker with factmsieve parameters too, so I think CADO will be even worse off against those.
Hi Curtis,

I still expect to give your params a test run when you get them set. I just can't see running CADO-NFS as a norm at this point, but I have a script alternative for msieve/ggnfs.

And, the results are in:

It was finished in just less than two days - 47h 36m 24s.

Let me know when you get some changes made for the params...
