Trouble is netrigger, both you and i come from a rigging background dealing with fish and fishing tecneques. Most if not all rabbiters wont have seen let alone used a trammel rigged with enough belly to catch and hold a bolting rabbit. As we both know the depth of the inner wall for fishing is vastly deeper than the trammels sold for rabbiting, this depth maybe being a cause of problem to rabbiters. However, i would have no fear of setting (not working) a modern rigged rabbiting trammel in the dark as all its running kill will be held in place every few inches or so, unlike a longnet.
Moley,
