We had the lines with hooks (chicken lines) on the Tiger we just sold and liked them a lot. Only used in really big swell and wind. In "normal" conditions it was not used. Only, only only hook it to the trapeze handle and NEVER the trapeze harness.
This is very, very clever! In this case one can use a fast eye snap or carabiner. Currently we have an open hook, but during tacks my main sheet gets very often tangled in this hook.
