Anybody ever fished this stuff?

It's cheap and I assumed it is crap, but my buddy fishes it exclusively (both leader and mainline) and is always one of the top producers on the river.

I witnessed him catch a 40 lb King in the Toutle on 12 lb Ande line. What the ?????????

I'm tired of spending $70 each year on the big spool of Ultragreen.

Is it fishable?
