Is anybody else is having issues with 'Basket' style Banana plugs. They seem to be the normal these days, the design is also used in some Electric Foil fencing Body wires - I'm an Armourer. It doesn't take long for them to loose their springiness and give bad connections. We've just bought a load of much more expensive 'traditional' style ones. The basket ones are definitely a false economy, IMHO.
