Super PE is by Sunline.
I've been using the Daiwa Saltiga Boat Braid for jigging for a little while now, and its great! Made in Japan, 8 ply, colour-metered, overtests (PE4/0.36mm/55lb) and an 1800m spool comes in at about a third of the price of varivas big one.
The PE3/40lb is 8 ply too, but they PE6/80lb is probably a little fatter than varivas, more a PE7. They also have a casting version, I have some of that on order to try.
