Interview segment begins at 43:02 I get regular and frequent questions on the differences between nylon and fluorocarbon tippet—when and where to use them, appropriate knots, special properties, and shelf life.  I used to be involved in the development process of tippet and have visit many places where tippet is made.  But that was years ago and a lot of progress has been made since my time in product development.  So I invited Josh Jenkins, R&D manager at Scientific Anglers, to talk about recent innovations in tippet material.  Josh is intimately involved in the development and testing of tippet for both Orvis and Scientific Anglers, and his knowledge is far greater that mine.  I think you’ll learn some surprising tips on both tippet material construction and knots because I learned a lot in speaking with Josh. The Fly Box this week is a little different.  This one was recorded live at The Fly Fishing Show in Edison New Jersey.  Rather than telling you what kinds of questions were asked (none of which were prompted or ones I had heard beforehand) I’ll let you discover these on your own.  You never know what might happen in New Jersey…
