>>Any recommendations on a static rope for aid climbing. I plan to use it
>>as a trail line when leading, then for hauling and sometimes ascending.
One thing to think about is if you are leading, then take a fall that
chops the lead line, then sail onto the static cord (haul line) your
spleen will probably pop right out of your torso when you hit the end of
the cord. Not pretty for the kids. A good system is to trail a DYNAMIC
rope (9mm,or 8,8 etc zip line) then at the belay station, haul up the real
haul line (11mm static), along with any extra items needed at the belay
(water, gear, jacket).
>>Is 9 mil the standard?
This is ok for smaller loads <100Lbs, but is kinda scary (mentally) for
jugging on. Honking on a beefy 11mm calms the soul.
>>How about 300 ft vs. two 150 ft?
A bit long is nice, like 200feet, but 300 seems too long.
>>What brands are most durable?
PMI seems to have a fine product, as does Blue Water.
