If you want a supple hooklink, then use standard Mono.
One of my favourite mono hooklinks is Preston Reflo mono, which I use in 10and a bit lbs for both floater hooklinks and bottom mono hooklinks, or a length of the same as my current reel line P-line Floroclear for bottom baits.
I think both are fluorocarbon coated polymers.
In fact I have found on a local lake with crayfish, that the mono hooklinks are less affected than a braid that gets twisted and fluffed to bits.
I have found straight fluorocarbons very stiff, preferring the ones above, or even 15lb Amnesia in clear for hooklinks.
