And one of the strongest of the 1/2" category line, next to the arbormaster series. Don't mean to knock opinions but shouldn't the strength of the line be one of the main features of a rope that is going to be used as a lowering line? The new neons and multi-stripes are all cool to look at and I understand the ID factor for the groundman, but my opinion the stronger the better.
Depends on the use, for general rigging you do not need 10k# of tensile, which is why I use retired climbing lines quite often. For me the cost is the biggest factor on a light rigging line, say for up to 200#, or so.
If you are dynamically loading, then you may want to look at the "modulus of elasticity" or stretchiness of the rope. On very short drops of high weigh, you may want a more static line.
I have a 1/2 inch super stretch double braid that I use for high rigging, but it sucks for pulling anything because it elongates without moving the load if i don't have a pretty high tie.
