@@jsc230 great question! I’ve recently fell in love with semperfli’s nano silk and been using the 30d size on all of my nymphs. I really love the slim profile and that it doesn’t build any bulk on the fly. Also, this particular thread is very strong I would classify its strength between UTC 70 and UTC 40. Occasionally I will break the thread but usually its because I knicked it somehow or if I go to crazy spinning a dubbing loop. The semperfli nano silk in the 50d is also a great median that doesn’t build bulk and is stronger. If you have not used this style and size of thread, I would recommend starting with the 50d and work your way down.
