I am very addicted to fly tying and try to sit down at my bench 4 or 5 times a week. My trout and lake boxes now have more than enough to get me through the year so I wanted to try some of the classic steelhead patterns. This may be a silly question, but whenever a pattern has called for silk I substitute uni floss. But watching Hans and others videos on the forums has me wanting to do it right. So how many of you actually use silk, or do you just use something like uni floss? What is the advantage of silk over floss?
