I use tacklebargins for all my saltwater and pike fly lines as they have some great offers.
If you had searched a bit more you may have found Berkley Big Game fly tippet in 20 and 30lb. Great stuff on wide spools. Ideal for Pollock as the stuff is near indestructable The abrasion resistence is superb. I also use it for my Pike as its quite stiff so turns over heavy flies just great.
