When using the off shore planner boards while trolling for walleye .I have been having problems with the line slipping through the clips. I modified/ upgraded all the clips and it’s happening still. When I get a fish on or run into weeds the line slips and  the flag does not go down. I just got the new modification for the flag too that just came out... didn’t change anything. Using 10 lb xt trilene. Any suggestions????
