don't listen to these guys. the route should be in great shape if the freezing level is low enough. go for it, and have fun. Just be careful about rockfall, don't stay roped together if you're not gonna put any pro in, don't fall, and climb as fast as possilbe. it shouldn't take you any more than 4-5 hours above thumb rock to the liberty cap. if you pitch anything out more than the last bergshrund headwall or need more than 1 rest breaks, you are going too slow. that's how people get hurt on this route.
