Thank you, Gimarel!
EdH's script already found a 1.327e15 spin after 1.5 hours of work. It's getting posted here later.

One good runner up so far with a different c6:

50100M also produced an uninteresting poly, 2.36e9 CADO score. I didn't bother scoring it on cownoise.
I'll take a break from poly select on this; if we go a week without anyone mentioning their own work, I'll proceed to testsieve a couple of the Gimarel polys / spun polys and report back. My university's finals are next week, so a testsieve update may be a couple weeks.

I'm getting about one poly above 9e16 every two days. But I have only one other poly above 1e15:

I got no sense that anyone particularly wanted to sieve this number, and lost interest by the time I had time for a testsieve.
I don't mind spending a couple hours on a testsieve, but I'm not doing that until I know whether I should optimize for a CADO job or a GGNFS job. On ggnfs it's best as a 33/34LP and our lim's are capped by NFS@home memory bounds; on CADO it could be any of 33/34, 34/34, 34/35, and lim's would be much higher and an open question for a testsieve. Ryan just sieved a C220 on CADO with 34/35 bounds; I await his data on Qrange and relation counts to help us make future determinations about when to choose among the above LP options.

I think it would be a very interesting number since 276 is both the smallest openended aliquotsequence which also makes it part of the Lehmer 5. But since I don't have any means to sieve this it doesn't say much, just that I'm interested in seeing the results... ;)
BTW, I'm still working on determining the dupsrate for that c167 depending on the qrange. At least so far it looks like there's a minimum at around qmax/qmin = 78 and then it increases again. Should be done by next week.

Post processing is another roadblock. Wonder if Greg or Ryan would be willing to help?
