I cannot imagine the foolishness of using a opaque furled leader. You might as well tie a foot or two "tippet" directly to your fly line. I find the extra knots to be fish losers. I have a few dozen tapered leaders left over from the large quantity I bought back in the 60's and these still work amazingly enough since they were kept dry and out of the sunlight. However, for the most part, I simply use 3 or 4 or 8 or 12 pound (up to 30 for chinook) straight leader from 200 yard Maxima spools. I use the stiff variety which casts almost as well as the tapered leaders. I don't fish fer bait fish so don't go under 3 pounds.
