Man Jim,
I think that we all can think of stories like that. I had that happen on a Lake Washington sockeye, my Son fought it to the boat, it did the "sockeye spin" and wound the leader up tight against he dodger and came off just as I was netting it, he kind o' fell into the net. I wouldn't worry about it, your client has a great story to tell!!!

Good luck and tight lines, Jeff
