Tex..... If you want to use silk , do so. Just thought you should now you dont have to. Many use nylon because it is easier to wrap and silk can be a bear if you have no experience with it. Whatever you choose have fun, and show us some pics along the way. Like above , the best part of the rod building experience is to catch the first fish on the newly built rod.........Good luck , ask away , and most of all enjoy the experience.....Ed
