My roll it up choice came down to either velcro or button snaps. I chose button snaps at Accessories Unlimited. A little harder on the fingers but a friend who had the velcro told me after several years his lost their stick. My Tonneau cost $345, in the box. They wanted $40 to install but it was easy enough DIY.
