The following cord comparisons will give you an idea of the relative diameter of 250lb Power-Pro compared to other popular cordage.

The 250lb test Power-Pro knots well and has sortof a waxy feeling. Obviously it is outrageously strong. I like this stuff so far. I'm going play with it for tie outs and guy lines. And I'm going to add it to my survival gear.

It is much too thin to use for hanging a bear-bag.

I paid $44 for a 150yd spool from Cabelas.
