Personally, I fished in Oman with nylon 300lbs.
As I use very short leader about 150cm, I sincerely believe that in this case this resistance is not necessary, 170 or 200lbs is enough for me.
In all my exotic fishing trip have never broken down on a leader but always on the braid.
When a beautiful GT takes a popper in 3 feet of water at 60m. about the boat for example, she needs 2 to 3 seconds to reach the coral heads nearest.
I must admit that I can't fishing with 17k. of drag
on the reel, perhaps it's the cause of my breaks down ( casse in french)
As always, it's just my opinion, I'm just a small fisherman, not in size but in experience
