Scientific Anglers called for the expertise of famed Florida Keys guide Capt. Bruce Chard to create the Mastery Textured Series Chard's grand slam taper. The line has an aggressive, short front taper that quickly transfers energy into the leader system, which is especially helpful for anglers throwing superlong leaders and big or heavy flies. An over-weighted belly allows anglers to instantly load the rod for quick and short presentations. In addition, the running line has an extra-small diameter that is good for distance casting. Match all these features with Scientific Anglers' texturing technology, and you've got yourself a line that increases the odds.
