Humm, it sinks."

Hummmm: 1.0 it just floats in pure H2O, should float well in lake water
and float great in sea water.

I have had Technora with Samthane coating (light spinnaker sheets from a
hobbie cat) as boot laces in my fire boots for 4 years now. Lots of
abraision, dirt, sun light and tight turns. They are still in great shape.
