In reply to sloper: assuming you're not doing this as a wind up, then here's my opinion...
1) don't f*ck about with a chockstone that you can't be sure of because
a) if it is a touch too small and someone lobs onto it and it pulls, then that is on your shoulders and
b) if it's too big and someone tales issue with it and decides to remove this jammed and stuck thing, who knows whether they'll use something other than brute force to remove it eg a chisel and crowbar
2) as has been said before, rocktalk is NOT A PLACE TO GAIN APPROVAL. many people on here are saddos who love the sight of their own cyberspace rantings but never actually get out and climb. go to the peak area meeting on the 30th, as i hope that simon lee character will.
cheers!
