Baran013,
Yea, I tried it as leader once, and didn't care for it at all. There's no way I'd spool up with line that high in memory. To me, the high memory offsets any advantage of the smaller diameter. Pinch it, and this is the way your line looks, "<." Tie a hook on, and you'll see this right above the knot, "~~~." Others may disagree, but I don't like it.
