If this has been posted before, please disregard, I didn't see it.

I love the furled leaders which were sent to me by board members...at the same time, I also love fishing long leaders, especially with mixed surface currents and eddies. I feel I get a longer drift (slightly). I have trouble turning over 4' of tippet at the end of a "standard" furled leader.

That said, has anyone used an extremely long 10-12' or better leaders for fishing other than Tenkara? Does it work well? Would grey thread negate the visibility of having only a foot of tippet out the end?
