I would defer to 7/16" by that point.
I use Yale ULS and its antecedent, UULS. Very soft on the outside, seems to be very kink-free, with lower stretch stats than Sta-Set/Sta-Set X. I am not a fan of NER at all - my longtime preference has always been Sampson XLS (new version: XLS3, available at Defender, Fisheries Supply, Vela, and a couple of others - check stock before getting your hopes up).
Awkward but true: the only reason so many people use NER at all is because Big Blue sells it (actually used to own it) and it's all they know. Ironically I bought all my Yale UULS from a West Marine (where I was manager) that was closing; it had been a BoatUS store and district management would not move the old stock to the new superstore if it wasn't still something WM would carry. I think I paid 0.08/ft for +/-350 ft of 3/8" (wicked laugh boowahahahahahahahahahahaha).
