In response to a request from a reader I have put together some thoughts on the relevancy of silk lines compared with modern lines.
The first thing to note is the diameter compared to the modern line (insert photo). A silk line is about 30 % thinner than its’ plastic equivalent with a correspondingly fine point.
A silk line has very low stretch and so, when hooking a fish the hook sets more firmly and the ‘feel’ in playing the fish is greatly enhanced and the angler feels more in touch with the quarry.
The working life of a silk line can be a long time with the minimum of care and very little effort on the part of the angler. In general, once a sportsman changes to silk, he or she stays with them for the rest of their fly fishing life.
