Ever since fluoro hit the market I've tried to accept it as another tool to use as it has it's advantages over mono, but I've grown to absolutely despise the stuff. Last fall I picked up a spool of this blend from Yo-Zuri and I gotta say I'm really impressed. I used it a few times last season, but I've really put it through the conditions I would use fluoro in if I didn't hate the stuff so muchon my last few outings.. Anyway, I think I have found a place for the Yo-Zuri in my 'tool box.' This is a great cranking line and outshines mono on my tubin' gear. The things I'm really impressed with are the knot strength and sensitivity. I have a tendency toward a very zealous hook set and that was the downfall of fluoro for me. Not a problem now. I did my 'cross her eyes' hook set on a couple of 3+lb. girls and not only did the knot not break, the sensitivity factor was the reason for my recognition of the first fish. The pick-up of my tube was so subtle, I doubt I would have detected it with mono. Manageability is still a downside as this stuff is on the stiff side, but a little KVD line conditioner and it became manageable.
For those of you that have given up on fluorocarbon lines, this could be an alternative. It even comes in an 'Ultra Soft' version that I haven't tried, but my ultra light is looking to get some 6lb. on it soon. (yea, I know 6lb. isn't exactly ultra light, but any thinner and I can't see to tie the stuff)
