I ran A5 to 5M and the best is:

3037^67-1 and 1481^73-1 have had sufficient ECM done by Oscar aka Lorgix.

I'm happy to push the C161; I really expect a C147, and probably a C155, can be handled locally in less time than waiting for it to get to the front of the 14e queue.

Yes, of course. The guidelines say C155 to C170 for GNFS. I am prepping Pascal's P+1 numbers and forgot which ones go where. Please ignore all postings for all numbers smaller than C155 - or C156 or whatever is right. I'll be more careful.

Oscar, aka Lorgix, has run ECM beyond 2/9 the SNFS size for

4001^67-1
3853^67-1

Another slow sieving 14e candidate from the xyyx world, C193_146_35. It withstood t50 by me with no factors found.

Sounds good to me; since you call it a 'slow sieving candidate' I guess you have a polynomial and parameters already. Post them here and I'll add them to the queue.
