I don't like the brand that uses the 6/0 method of measuring thread. I do use a couple colors in 6/0 because I can't get that color in Danville or Ultra thread which are my favorites as far as thread goes. Don't think it gets better than these 2 threads! So get some thread that uses the denier size for their thread and get flat waxed! 210 amd 140 are the best for jigs, but flies are different and many times you need much thinner thread.
