It's a good thing you backed off Mikl,
I was out there with a mate in spring, and we decided to rap down bartons, to check out the expansions...
The 3rd or 4th snapped about 3mm into the rock with an outward quickdraw into harness pull... rusted through
Looks like it'd be mighty scary now as its a long run out off an rp through what looks to be the crux...
My mate wrote it up on chocky a few months ago...
Maybe chocky could make a dangerous climbs forum by area... Or people could just check with ACA..
As it happens when we were out there we got shat on by a pretty big thunderstorm whilst we were halfway up the corner next to Bartons Effort..
The "immaculately brushed line" was infact a waterfall deeper than the fixed hangers!
