The prince exo3 Silve 118 seems to be the worst in tension loss.
There are three points of friction when pulling tension using a boomerang (two points on the boomerang and one on the frame) and each point will reduce tension. Then there is the issue of using the boomerang that fits in the hole and does not pop out. I don't like using the boomerangs and would prefer my string method or I think a spring loaded clothespin would work great. it should not be hard to fabricate a tool either shaped like a U to drop over the frame.
