What thread(s) do you use for tying small flies (into the 20's)? I've been researching veevus and see the 12/0 to 14/0 seems to have a breaking strength of about 18 ounces. I've been using 6/0 and 8/0 tying thread as that's all I have and it's getting bulky on the flies. 6/0 is the worst and I can see I'll have issues with some of the smaller patterns with the 8/0. So, recommendations for a semi-heavy handed tyer who thinks 18 ounce thread might be an issue. What do you use and how do you like it? Guess I won't be tying any #24 muddlers with that thread.
