From Semperfli:

'Semperfli Spyder thread has been a long loved thread for tiny flies. Now we have taken it to the next level with 18/0 Classic Waxed. 18/0 Classic Waxed, a traditional tying thread, was specially developed to be semi translucent so that the threads help adopt the shade of the  fly  pattern.  18/0 Classic Waxed has 2  fine  strands  of  thread  twisted together. It has a breaking strain of approximately 400gm - for comparison tests show Uni Caenis to have a breaking strain of 85g & Danville  Spiderweb  breaking  strain  is  approximately 142gm. The strength of 18/0 Classic Waxed in comparison will give the fly tyer confidence when tying small flies that their thread will hold better.  With 2 strands 18/0 Classic Waxed will also lay reasonably flat  when tying flies. 18/0 Classic Waxed is  aimed  for  fly  tyers  wanting  to  tie  small  flies  as  an alternative to threads like Uni Caenis or Whisp which are weaker threads. In developing 18/0 Classic Waxed the team wanted a micro thread which had some strength, laid flat.
