I have to admit, I chose the first option, but I do put my back seat back in maybe once or twice a year, depending. Zeus's method for removing it with the pins from Ace is great if you think they will come in and out often, otherwise just remove and put the bolts back in and put a rubber bed liner over everything. That's what I did and its all nice and flat. I love it. I can fit everything I need.
