Re: 1/2\" stable braid or super braid.
Yeah.... um...
Anywho I dislike Super Braid. Its stiffness trades off considerable strength from my informal testing.
For the test I tied interlocking bowlines in the end of safety pro 12 and superbraid (both 1/2"). A fairly accurate synopsis was out of 10 times, the superbraid would break 6-8 times reusing the unbroke bowline. The safety pro is rated well below the Super Braid.
For 1/2" I perfer a 16 strand, however I do have 1/2" Stable braid and up to 1 1/8" doule braid from samson.
For stable braid my most used size is 9/16" but the 3/4" gets used a good bit. The 5/8" gets used also, but normally its either big or small, not too much inbetween.
