Crummybun:
That is the same stuff I have been trying this year. I think most trolling data charts that I have seen seem to lean toward 2 mph as the “standard” for speed. I know that the “advanced” stuff has a smaller diameter than the standard stuff and that difference in diameter is theorized to allow it to run deeper for that reason (less drag = more depth). Of course, I am relying on gps data for speed, which I have learned, here on the site, can be way off, due to current. I tend to troll at around 3 to 3.25 mph by gps, though I vary it intentionally if that’s not working. I know that increasing the speed significantly will decrease the depth I am achieving, but, I have not seen any data on how much effect it might be having. I didn’t have any rods with 10 colours spooled on to them, so at one point I had 7 colours out with body bait that is supposed to dive to 20 feet and still did not get any fish joy. I did vary it from 5 all the way to 7 colours out, thinking I might have been too deep, but it still did not generate any action.
I do believe that a couple of weeks ago, with an RRF out on a 10 ft leader behind 7 colours, I was making some bottom contact in about 52 feet of water. I thought at first it was some tentative walleye bites, but it all stopped once I crossed the 54 foot threshold and did not repeat as I continued out to deeper water. I may have to spool on 3 more colours before the season is over to see if that produces anything. In the meantime, the dipsy divers have producing well at around 150 back so I am mostly relying on them lately.
Sorry f.g.p. I think I highjacked your thread - not my intention. Over and out.
