More than just fly fishing
Bass Tournament Fisherman's Testimonial...  (Size 0X and 1X)
I have used P-Line Premium Fluorocarbon Tapered Leaders for years and have never had one fail. I used these in Bass tournaments and in the Bassmaster Classic Regional Qualifier on Okeechobee to limit out every day.
I spliced into my P-Line Braid and used it on my spinning gear for flipping in the bulrush and punching mats. The sensitivity, abrasion resistance, near invisibility, and overall pound for diameter strength is unmatched.  It didn't matter if I was using 0X or 1X size, the fish and vegetation were no match.
If this leader will hold up to, straight up muscling bass out of heavy cover I am sure it will handle fly fishing conditions just as easy.
Other applications I have used P-Line Fluorocarbon Tapered Leaders for are clear water lakes.  Flipping finesse jigs or shaky heads on dock post and in open water with spoons and jerkbaits.  When using it on suspending jerkbaits, it will outfish all other most any other lines.  Invisibility and the ability to take a bait deeper than any other lines make it the best choice for open water long casting. The weight of the line just adds extra distance for any of the weight shifting high performance lures. So many applications other than just precision fly fishing. Transformed my light line spinning rod into finesse power fishing.
