I use Wilflex Silver Shimmer, and also gold made with Silver and PC. We run it through a Sefar 123-55. One stroke, no PFP. (Now my little bitch. "Thin Threads" have been around many years. I've been using then in certain mesh counts for over 15 years. Someone finally decided to promote their benefits. It's not the new miracle mesh some make it out to be. Good mesh? Yes. New? Nope)
