jack rabitt or roll bak?

[easydays]

am trying to decide beteween jack rabitt or the roll bal
08 tundra double cab 6.5 bed with utilitie track

they are both around $ 800 at [url=http://www.aztrucks.com[/url]
both have cons and pros

jack rabitt has a lock cylinder on the top and you can open the cover with out opening the tail gate, but the thickness of the aluminum plates is very thin

roll bak has no outside cylinder lock you have to open the tail gate to open cover , this makes it more secure and you dont have to add another key to the key chain , and the tickness of the aluminum is way thicker

any one have expirience with these roll up covers
