I wish they'd all show the measurements of their tapers. Some do, most don't. The WF market is a nightmare. Some are like casting a Rapala. Some are nearly level.

All I need is a DT and a WF, one "standard" taper, in the weights that work on my rods. The terms "Tarpon", "Striper" "Redfish", and all that are meaningless. Just like "light, "medium", and "heavy" to describe rod actions. No two are alike, despite the name. Tarpon come in 5 lb sizes and 150 lb. sizes. Same line? I don't think so.

I agree with the OP. Make two or three tapers, put the best finish on them that's available, maybe make a WF that's stiffer for tropical applications, and let us all learn to cast them all. There's no reason other than marketing to have 10 or 15 different fly lines. PT Barnum would have done well in the fly line business!

And to the guy who said Cortland 444 peach---YES!
