Mate,
I went with a McHitch. I have electric brakes on the CT and a controller in the tug.
I have a hand brake on the trailer as well and didn't want to have to change to much.
The McHitch allows me to have both the electric and mechanical brakes working. But I zipped tied the mechanical brakes off and use only the electric brakes. If something goes wrong with the electric, I can use the mechanical to get me home. I got this idea off another swagger!!
I just like to have a back up, especially when it comes to brakes and my trailer being 1000kg. If it's over 750kg, you have to have a brake system on the CT.
