A furled leader is long lasting using a loop to loop connection for the tippet. A furled leader will last a season or more.
They have little to no memory, no "Slinky" on the end of your fly line.
A furled leader can be cast just like a fly line allowing the use of longer tippets.
Excelent presentation.
There's much more and I'm sure otheres will be chiming in.
