I have been trying to furl a leader using flurocarbon and have been unsuccessfull as of now. The first time I tried it with Sportsmans Wharehouse Fluro and it broke snapped. Second time I tried to use Rio Poweflex and same thing happpened, but I did have enough left to be able to connect and redo the first leg. This time instead of breaking it crawled up as I was hanging it to unfurl and combine the two legs. I am guessing that I didn't have enough presure on them as I was furling in fear of breaking them, as they are very pricey. Why is the Fluro so hard to furl in comparison to my thread leaders? I have no problem what so ever with them.
