Bamboozle, I was making my .005 comparison based on what is listed on the Bass Pro Shop website.
http://www.basspro.com/webapp/wcs/st...ems#itemDetail. On that website it lists Berkley Vanish 4lb as .005 in diameter. However on Dick's Sporting goods, its listed at .007, MC Sports listed as .007, as well as others listed it at .007. This in and of itself makes me question the consistency or accuracy of the listed diameters on fluorocarbon fishing lines.
