Haven't read the links yet but I have strong feelings on the subject.
This is perhaps the most important issue facing the next generation of climbers.
I don't think that faster parties automatically have the right to pass.
A friend of mine was making excellent time on a crowded arete when his party was overtaken by some crazy euro speed climbers who were yanking on everyone else's gear and even their ropes! Right above my friend one of them pulled off a huge block that my friend had to dodge.
He then watched in horror as the block killed two climbers below.
The euros continued on their merry way.
I believe that crowded routes should have a consensus window time bracket.
If a party is keeping within that window then it should be their option as to whether a faster party can pass, thus exposing them to potential rock (or gear) fall.
Slow parties who can't even climb within the window should get the directions to Carnegie Hall.
Go someplace not crowded and practice.
hah! I'm barely up there. I just post a lot and like to talk climbing, not so much politics as you might have noticed.
anyways, one example i have is trying to do SFWC in a push. we started at midnite and got up to the base of the kor pretty amped, but there were fixed lines and we were planning on catching some quick zzz. team of euros sleeping at the base. we felt bad as we didn't really want to wake them up. we bailed after trying the bypass without the right gear.
meh, live and learn. we should have just asked to use their rope and wake them up. or just climb over the top of them since they were still more or less sleeping. one of them kept eyeballing me tho.
