Single T-Lock vs Double T-Lock

On the rear window is there any benefit to getting the double T-Lock handles. Does it close better with the two on the outside vs just the single one in the middle? More secure? Etc? What are your opinions?

 

I went with the single. It is actually more secure with the rods. The double are just a little latch that that tilts up and down. To me it would be a big pain in the ass to have to open two locks every time I wanted to get in the shell. I actually thing the T handles are better than the wires used on the upper level caps.
