You could use it doubled up for purse nets, but it would still be light.
I just made a 25 yard long net out of it and would recommend it to anyone for making long net but not for purse nets. Just for info the 1.2 kilo spool will make the body of a 50 yard long net at 13 meshes deep. It knots like a dream and is really very nice to knit with. If despooled correctly it does not twist when loading needles.
