Gentlemen:
Hope I am not resurrecting too old a thread. All of my popping rods have graphite seats, so when I use a harness, I do one of two things:
(1) I use the Smith Smitty's shoulder harness. this goes to a strap with two D-rings that wraps around the reel seat jut forward of the reel stem.
(2) Superior to this (in terms of fighting ability) is a product made by Braid called either the "reel rest" or the "rod rest". This too is a short strap with two D rings, but there is a slot on one side of the strap through which you put the other D ring. Then you hook it up to your butt harness for standup. It is wonderful.
