If it's the same Sufix I used (not sure of the spelling) it was an Italian line I liked for bloodworm and punch fishing in .06.
It was rated at a much higher poundage than other lines, the claims were true.
On my own test .06 broke around 2.5 pound, is this the stuff you mean fichie.
The last time I found some was from Godmalding angling about 5 year ago.
I don't know if they are still trading. If they are and you can find their number he may be able to help.
I know he told me he was trying to get a franchise to be the only supplier in the UK, I used to check with him weekly but I got browned off making weekly calls with no joy. I looked for his number but can't find it.
Sorry for the long reply fichie.
By the way if you do find any give me a nod please.
