Help me chose a tonneau cover

I use a Diamondback HD. Diamondback offers a few different configurations. I chose the HD because it can be opened from the front or the back and the two panels can be removed to expose most of the bed. Also with the HD series, you can carry just about anything you want on top of it leaving the stored items secure underneath. I've had the cover for over five years without issue, other than a torn gasket. Diamondback replaced the gasket at no charge.
