In reply to Toby M: Nicely made screws- good quality steel- tapered inner etc. the little bumb allows them to be placed reasonably quickly though not as fast as the bd/grivel ones. thing that gets me is the big hefty hanger- designed to be smooth enough to allow the rope to be run through it for abseils-- haven't they heard of V-threads, much more preferable than leaving behind a 35 squid screw?
