I’m not going to name names here regarding the bad experiences that I’ve had with ropes, but suffice to say I’ve got my 'Yes' and my 'No' camps. After testing the Boa 9.8mm, Edelrid are definitely a 'Yes' and as such I’d even consider checking out one of their more specialist, skinnier options like the Corbie 8.6mm as a specialist tool for long, pumpy on-sights or redpoints.
