Hi Craig,
Yes, we only have 1 rigger plus the lead core set ups. Based on YO's report the other day, we just kept the rigger at 36 and got the last salmon of the morning at 40 feet. We never varied from there. And YES, the 4th rod was indeed buried at sea as we were setting up...loose rod holder, almost tossed everything else in after it,%$#@! As for marking fish, it was weird as you could see the thermocline but there were as many individual large sized targets above it as below it in some spots. Of course it was totally overcast, dark and rainy, not sure how much that matters but I'm sure it had an impact. Also, all fish off the riggers were only set back 6-10 off the ball. I painted the rigger ball hot pink, loaded it with reflective tape and added a couple sections of spinners above the ball.
Just a great day.
