Favorite banana plugs?

For me, Furutech is the best speaker cable banana-plug termination: https://furutech.com/product/fp-202-r-g/

For test equipment I prefer Pomona high current banana-plugs/jacks. 

Be careful with the Viborg bananas; they can bend and get loose easily with heavier cables like Mogami 3104(9awg) that I use.  Right now I'm using expensive WBT 0610 locking binding posts.  I have some very similar looking (Preffair?) from Amazon, but have not tried them yet. But side to side with the WBT's, they're not the same, particularly how the locking mechanism works and the screws to attach the cable seem less robust.  Every WBT connector I've tried can be used over and over again, unlike most inexpensive Asian alternatives that I have tried, but like the age-old adage: you get what you pay for.  Still looking for some BFA's because they look, on paper at least, the best type of speaker connector.

..plugs should match jacks, e.g. pure copper (tellurium copper) plugs are the best if jacks are using the same metallurgy process/materials. gold (or other) plating can be bad, if gold comes on top of nickel or other interlayer metal, instead of direct deposition on core metal. 

I 100% agree with westcoastaudiophile on furutech fp202g or r for rhodium.  I used the aliexpress copies and when I switched to the real furutech it was noticeably much better mechanically

Low mass, tight fit, better than my WBT610s on low output tube amp.
