I purchased to Adams spools, a 1 and 4X. My 1X leader is 30 feet of 1X Adams, 3 feet of 2X Soldarini 2X tricolor sighter, tippet ring, then tippet of choice and length below. The 4X leader is 30 feet of 4X, 3 feet of 4X Soldarini tricolor sighter. I have only fished the 1X Adams leader so far. I don’t have much experience casting and fishing leader this thin so I don’t have a point of comparison. It cast reasonably well, though it did require better backcasting technique in my hands than the stiffer butt sections I normally fish. Where I thought it out fished the stiffer leaders was in sensitivity. I felt I could see more subtle takes, and the feel through the line helped me be able to distinguish bottom structure better than the stiffer lines. I also though it sagged less that allowed me to fish at a little greater distance when wading conditions required it.
Thanks all for your thoughts.
