Re: Swing weight question ?
Read Silver's explanation and my eyes glazed over for a second. But he's dead on right. Only personal observation I could add is I like to slightly 'over reel' fly rods so they move slighly 'tip high' on the swing. Much easier on the wrist/arm/should over a long days fishing.
