I thought I had found the perfect solution in the rigging of my spinnaker, and in fact it is easy to rig and works well.
What I do: The clew of the spinnaker has a short line spliced it it, and the sheets are composed of a single continuous line which I middle, and sheet bend the clew line to. Works great

.... except.....
After a boisterous sail that sheet bend is chinched so hard there is no hope of untieing it.
Does anyone have an fix more elegant than two seperate sheet lines bowlined to the clew of the sail? That will obviously work, and will always (almost) untie, but I just have a feeling in my bones that there is a neater solution out there I just haven't had enough experience to hear of...
Is a double sheet bend less likely to jam tight?
The boat is 40 feet LOA, with an I of 49.3 ft, J of 14 ft and the sail is about 600 sq feet.
