I believe you will find that the Hopkins works about the same way as the P2 & P3. That is there is a preset amount of braking in conjunction with the brake lights. Then the pendulum effect takes place according to your tow vehicles ability to slow the combination. In my opinion, choose the one that mounts like you want it.
With brake controllers being controlled by brake lights and accelerometers, is there any wonder that hitch play might be annoying? My preference is brakes controlled by the operators foot pressure, like factory units.
