Personal belay / lifelines, ropes.

Our expectations & reasoning behind this.
These ropes are more for use away from the van when traveling, or possibly wading to check the depth before a river crossing. Definitely not for towing or winching the van.

Currently, 3 to choose from. 8mm semi-static, 9.1mm, or 11 mm dynamic.

The 8mm (white) is semi-static and the most used (by us), the other two are dynamic and although easier to tie knots in, are heavier so less favored if they need to be carried any distance. None of these ropes float. the white rope is fast approaching its retirement date and will need replacing soon. The 11mm dark green will also be replaced with a 9.1mm rope in the not-too-distant future as well.

More photos, info, and write-up to follow ASAP.

In-use reviews.

Pros.
8mm (semi-static).
    Lightest to carry.
    Less stretch when loaded.
9mm (dynamic).
    Better shock loading should one fall

Cons.
8mm (semi-static).
    Higher shock loading should one fall.
9mm (dynamic).
    Softer rope, so easier to tie knots in.
