I've done ok with Aiken Concept2000 (4lb), WB clarke Matchline (6lb)when used as a hooklength material whilstfishing on the float, and a mate of mine who does a lot of pole fishing uses the Dave Harrel stuff (MAP carp???) or something like that.
I've also used braided hooklinkslike of Drennan Sink Link which is good and I know
kryston do loads, I've usedKryston silkworm for years. Theseare whatI often use if amlegering, as opposed to float fishing. These are often thicker diameter wise,but much softer and very strong!
If you want a fluro hooklengthhave a look at Virage in 10lb.
