The SA Mastery Bass Taper is worth every penny. I wish I could put it on all my heavy duty rods. I have it on an 8wt, I use type 3 and 6 sinking leaders (the one's that usually cast like well ropes) and throw metal fly rod lures (spoons, jigs, in-line spinners) on it with ease. It's an amazing line. I'm sold on that line. It handles distance well too. Just to push the line I cast a heavy dumbell eye zonker/bunny type streamer on a #2 saltwater hook 60 ft with no problems. It really shines while boat fishing. You do have other options though: some saltwater lines with very forward tapers work well, pike and musky line will work too. I've not found a better heavy line than SA Mastery Bass Taper, but do pair it up with a proper leader. For floating leaders I use the super stout, 4' long bass/pike type leaders. Don't skimp on the leaders with this line and it will suit you well.
