A medium rod has most of its flex in the top half of the rod leaving the bottom half stiffer. A fast action rod has most of its flex in the top quarter of the rod and will be stiffer in the middle and butt section. Progressive Taper A progressive taper is a rod which has a smooth, even increase in thickness all the way to the handle. A rod built to this form will get increasingly stiffer towards the handle, therefore the more load that is applied the deeper the rod will flex. This type of design is good for casting at short, medium and long distances. Compound Taper This is basically a progressive taper, but the increase in diameter is varied along the length of the rod. Most of the old classic tapers were made to a compound taper. Parabolic This type of rod will flex more in the butt section when a heavy load is applied. They have a stiff middle section and a flexible butt section. Rods with parabolic tapers are slow and powerful and make fantastic roll casting rods.

Do men really want to understand women? What is the unifying field theory of atomic and sub-atomic physics that solves the current impasse of dark energy's affect on the constant of gravity? ............ But for a good try at an answer, check out Ed Engles book Spitting Cane and read in the section on George Maurer, bless his life and talents, and his understanding of a parabolic action. Just remember, that rod action is a matter of taste and taste is a matter of passion and passion is a matter of spirit and spirits come in different proofs.

Posts: 1994 06/10/2008 16:00 Moderatus Muscae	The question was asked a month ago in the rodbuilding and restoration forum, and several people made helpful comments. See: http://clarksclassicflyrodforum.yuku.com/topic/14615 Quashnet's Paul H. Young Rod Database has photos and descriptions of 290 PHY Co. rods, plus catalogs, accessories, etc. Thank you to all who continue to send me PHY rod photos and info.

Posts: 361 06/10/2008 22:15	I think that maybe the most important thing for a newbie coming over from Graphite to know about paras is that they generally demand a significantly different casting stroke, one that sort of calls for pauses as the casted line unfurls, then flexes the rod deep into the handle, at which point you can start to move forward (or backward as the case may be). For me, out of all modern bamboo rods, the hard-core paras require a casting cadence farthest from that usually employed by "fast-graphite" casters. For that reason, I tihnk, it's rare for a newbie to move directly from graphite to parabolics. Paras are treasured (by those who treasure them) for their great weight-to-power ratio, since almost all the bamboo is actively used to project line forward and backward (as opposed to say, the top 1/3 of the rod...), and also for the great "feel" that they transmit from fish to tippet to line to rod to hand. They seem an acquired taste to me, just as oysters ("Twas a brave man what first ate an oyster"), asparagus, tete de veau and vin jaune are. Hmmm, I guess it's supper time. All the best, Lee
