I’ve used Ultra Thread 70D for several weeks on my dry fly and nymph patterns. The thread holds well and doesn’t fray easily. It’s especially good for small hooks and gives a clean, tight knot. The nylon stretch helps with tension control during tying.

This thread performs better than the generic ones I’ve tried. It’s smooth to work with and stays strong even after repeated tying. I use it mainly for midges and size 14 patterns. The low bulk is a big plus.

The consistency in tension is noticeable. I found it easier to tie small hooks without the thread slipping. It’s a reliable choice for precision tying and has held up well in the field.
