Re: Leader building
I find that a leader that comes off the reel in coils can be straightened in 3' sections just by stretching it with almost your full strength. Obviously this works better with the thicker sections. A tippet can be drawn through a piece of rubberized shelf liner. I carry two 4"x4" sections of this in my vest for pulling ferrules apart, should they stick.
BTW, contrary to the advertizing, you don't need to buy new leader material each year. Just keep it out of the light and Nylon will last for 30-40 years. I am still using leaders made in the 1970's. (I cut the tip sections from any knotless old leaders; the extrusion technology was sometimes poor back then.)
