I agree the making of a furled leader is not rocket science, but i just like treating it that way. Had some in depth discussions with dman and aged_sage on the furled leader forum and loved it. If it has not improved my furled leaders, it certainly helped in understanding why furled leader work that good.
As i live in europe i think i'll not meet both of them ever, but i feel like i've found some friends online. All just because of treating furled leader making as rocket science
