Re: poly leader vs versi leader
Versi and Poly are basically the same poly comes from Airflo and Versi comes from RIO. For dead drifting just a plain old 9' mono leader with tippet is fine, for swinging flies the poly/versi's range from a floating to an extra fast sink. Depth and current speed will influance what weight to use.
