Thanks for the explanation. I watched the video and like what I saw. I started out with the conventional pinch pads. They're fine for slow trolling. Adjust them for one speed and your good. But I like trolling at all speeds. I frequently troll at 4 mph and pinch pads weren't holding, that's why I went to blacks. But what I'm seeing with chamberlain's caught my attention. Going to pick up some and give them a try. Thanks! Sent from my SM-G920V using Tapatalk
