Like WarrenP, I only tried the split thread method since I've started watching Hans' videos - I've used UTC 70 and Benecchi 10/0, and Danville 8/0 and so far all of them seem to split pretty easily and be strong enpough for most of my needs. I haven't done enough with any of them to have a favorite. In general I think the less bulk the better so I generally don't use 6/0 or 140D unless I'm working with hair or Foam.
