Perhaps this is not the correct location, but I have question:

I have a 37ft shooting head for my switch rod. I got a running line that is rated at 20#. The shooting head has a welded loop at both ends.

How would you connect the two?

Should I make a loop in the running line and wrap it with a whip finish?

Should I cut the loop off from the head and tie together with a blood knot? If not a bloodknot, what knot would you recommend?

Is there any other possibilities?

Right now, I did a 6-turn surgeon's loop in the running line, but it bangs like hell on the guides when I'm shooting line.

As always, you guys are the best.
