Thanks for clearing that up fishin fool,I should have said "reverse streamline approach".. As far as the 20 to 50 I always double the 20 with a bimini,spider or triple sugeons,caught cobes up to 80,but I'll experiment with one over 100 if he takes the bait .Guess doubleing the 20 is sort of like a tapered leader,but it's [email protected] on levelwinds that way.It maybe good for that application,just like tieing my own(especially for those kind of $).Generally,I don't use a levelwind anyway when shock that heavy is required. Using 6 diameter fireline to 20 or 30 flouro with a double uni when I'm using a levelwind for lures and such,and had good sucess with it..fishin fool2 said:The tapered surf leader I have seen is attached to the main line so that the two small lines are tied together so the knot is small. they are much longer than the usual shock leader. They get larger as you go toward the hook end. the last 20 feet or so will be the strongest portion. The opposite of fly leader. With say a 20 to 50 taper you can tie the 20 to your main line have a small knot and still have a 50 lb shock. I just use 50 lb shock and larger eyes on my rods. I do think It would work well for levelwind reels though if you need a shock leader and need a small knot. But so does power pro. The main concern of mine would be the strenght of 20 tied to 20 vs 20 tied to 50. You experiment on a 50 or 60 lb cobia next year and get back to us.
