I am interested in other people's opinion on this.
It is always good to find out what failed when a boat loses its rig.
Today we had wonderful B rig wind for our fleet race. Two boats came together going upwind and one of boats lost its rig. The skipper said that the PeKaBe hook on the swivel/string at the jib rack straightened out causing the rig to come down. To identify it, that hook is the one that has a little reverse curve at the tip of the open end.
Those hooks are soft steel. The only place they should be used on an EC-12 is on the sheet elastic where they will never see a shock load. Every other place on the EC-12 - backstay, jib stay, sheets lines... Those hooks are not strong enough to handle a good sized shock load.
Good strong hard (stainless) steel hooks, but not the standard PeKaBe.
