WBT Banana Connectors

Look at BFA style.  many options but make great contact, are one peice, and low mass.

Prong seperation is one of the main reasons I like BFA.  Most people don't realize how many pieces there are to a traditional banana plug.

Here are my favorites.....low mass

Those z plugs are what I call BFA.  I'm just going by what I've seen them called.
