I have been using Lefty Kreh inspired "supple butt" leaders for most of my angling for years. Maxima Chameleon can be a bit too stiff for butt sections in my opinion. That loop needs to roll, it makes sense to me that it be made of material that wiil allow that. I use quality mono such as Trilene or Ande. Whatever brand you choose, keep it the same throughout the butt and midsection for consistant energy transfer.
