Re: Leader requirements?
Part of the purpose of the leader is to taper down in stiffness and size from the fat flyline to the thin tippet. If you went from flyline right to thin tippet (like riptide said, you can do it with thicker mono), the knot would act like a hinge and the line would pass the fly or get all tangled up.
God does not subtract from man's allotted time those hours spent fishing.
