Braid has about 3 to. 10% depending on brand & content.
Fluoro product is similar to mono in some ways.
It is based on carbon content & some can have a mono content , therefore 100% fluoro content is generally the best !
Fluoro has about 15 to 20 % stretch where monos can go to 30 % +!
If UR missing fish with a short fluoro leader attached to braid then u should have more than enough to set any hook since UR leader is oh a few feet in length,
Bear in mind lighter test fluoros will allow for more stretch but not anywhere near what u would expierance with similar monos !!
I fish with fluoro UL lines exclusively not leaders ,complete lines.
No issues at all and have taken numerous trout over 5#'s to 9#'s over the past four seasons all on 4# line .
The best fluoro lite line by far is Blackwater not cheap just the best !!
If problem persists ditch the braid go all mono or fluoro, braid has no benefit if UR stream trout fishing , it's the last product u need to ultra light fish effectively !
