I use 9, the maximum setting, most of the time. I use the lever on the bottom of the remote control to be sure the Patriot applies the toad brakes every time we hook up, and I've never had the toad slide the tires. That tells me that it's not applying too much braking force. Normally, I want as much braking action as I can get. When I don't want the toad brakes to be applied, I just dial the remote back to zero.
