thread choices

[Steven]

Lately in tying videos it seems that UTC 70 denier (6/0) thread is becoming more and more common. The standard in my old days used to be Danville 70 denier (6/0). Both seem to be quite similar nylon with the UTC costing about twice as much. Can someone bring me up to speed?

FWIW, I was under the impression that 70 denier was closer to 8/0 than 6/0. 140 denier would be the 6/0 equivalent.
Am I wrong on this?

Edit to add: I mostly tie with Uni Thread in 8/0 or 6/0 and whatever Orvis sells (there's an Orvis around the corner from my condo) in the same sizes.
