Would u put a swivel terminal and then the panther Martin?
Yes. I usually run a snap swivel to the PM so I can change lures and keep line twist down.
I lost a big cat after a good full minute fight when my snap apparently came open.
Whether I was putting too much pressure on it or if I just screwed up and didn't get it closed properly (most likely) I don't know....
The best setup is to put a small split ring and a swivel on the PM while changing the hook to a siwash - then just tie direct. It's more trouble, but a stronger and shorter setup.
