Another thing I like to do when trolling our lakes around here. Because we have so many snags here, standing timber and stumps below the water line... is to set out my line at the desired distance and then back off the drag until line just starts to "bleed" off the spool, then tighten down my drag just a smidgeto keep line from "bleeding" off the reel. Then when I get a fish on I can adjust the drag just a little tighter if need be, if I hook a snag... I knock the boat out of gear and bring in the other lines and go back to unsnag my lure. That's when the PP and Spiderwire come in real handy!
I hope this helps!
