It is pretty supple for floro. It will have less stretch than nylon but I find it knots very well and is ultra reliable. I use 10lb breaking strain for most fishing nd only go down to 8lb or 6lb for ultra spooky fish. The floro I used before which was highly recommended I lost fish after fish, particularly on smash takes. This one, I haven't lost a fish through a break in 2 seasons of using it. Worth a try mate.
Its expensive but you will get a lot of hook lengths out of it, unlike fly fishing where my usual leader is 22ft of the stuff + up to 3 droppers. You get through a few spools in a season!
