I submit this picture to you:
See all that skinny running line to the right? If you analyze it a bit, you notice that "running line" is actually a buzzword for "cost savings"! Selling you a WF line with less material for the same price as a DT or level line! The extra plastic is filling their pockets!
The molded "casting bump" on some WF lines? Extrusion defects. "SA Mastery Sharkskin/Textured" lines? A graduate student was in charge of the finishing on one production run and graduate students are cheaper to employ!
Using the new terminology, a shooting head is roughly "30' of heavy head looped to 70' of cost savings".
