Sounds like a great idea for a sidebar activity. Back in the old country I won a few bets with the Bimmini twist. Most of the freshwater anglers I knew had never heard of it. They all believed that a knot which would test at a higher breaking strain than the line did not exist. Oh what fun watching the disbelief on peoples faces when handed a 21 turn bimmini in 4lb test which, however hard they tried, simply refused to break at the knot!
