Eddie,
I would not bother with an expensive cold saltwater line, because if you are in real Pollock territory, your line will get damaged on the rocks.
I used to use an outbound, brillient line, but when a Pollock dives deep and your feel the line grating across barnicles, and then see the damage they do, you will see why I get the Airflo lines at £15
I also use shooting heads by the way. That why I can use a tough mono shooting line that if it gets damaged, I can just cut back and re tie.
Besides, there are not many lines about besides the Airflo for cold saltwater, so you may struggle to find one.
