It's very very fine diameter 0.14 down to 0.1, my go to is mono is 0.23 6lb, why do you want/need it so fine?
To those who say not to bother lubricating knots ...
A few years ago I had the good fortune to attend a talk by Peter Morse. Morsie holds at least one world record for tropical saltwater species caught on the fly. He is one of the people who I will listen to and learn from when it comes to knots.
One demonstration using 70lb nylon monofilament was to rub it with a dry paper towel, simulating the friction of tightening a knot without lubrication. The 70lb mono could be easily snapped by pulling.
@chiron: JT, a hugely successful competition angler, is another person who I will listen to and learn from :thumbs:
