I have the MKA-32. I have not used the other brackets, but I am very happy with this one and would buy another. Removing the motor literally takes 5 seconds. I also like the cover for a clean deck when the motor is not on the boat. The only time I go without the TM is in the spring when sturgeon fishing.
I have attached a few pictures so you can get a feel for what it might look like on your boat.
You are going to love your Terrova. Moving from my Maxxum to the Terrova was one of the best decisions have made for my style of fishing.
