I think JR may have done/ tried this. I remember him coming in for a ton of heckling as he battled up Tower Chimney. It might have been some other challenge they were trying though.
And one final thing, remember downclimbing routes doesn't count, unless you're name is arran or ohly.
Cheers JR. I'm aiming for minimal leading/seconding. As I can't find anyone so far who'd want to do it in this style I'll prob only have partner on the led routes. Hoping for a <10 hour completion this way!
