I considered using GNFS, but the SNFS poly's e-score is better than the record for a c174.

Keep in mind the record GNFS score is based on degree 5 (for a c174) but your SNFS is a degree 6. They don’t directly compare unfortunately.

Comparing test sieving results for degree 5 and 6 with the e scores they are not far out. So I don't think I could find a GNFS poly for 60^139+1 that would save more sieving time that it would take to find it.
