Easy Bumper Switching?

[RobotsQ]

Last season we attached our bumpers to the robot by putting grenade pins through L-brackets, but after having them jarred loose and finally having them fall off of the robot in our first match of competition, we were forced to make the switch to nuts and bolts. However, even those fell loose in our second match, forcing us to use nylock nuts. This was less than ideal, as all 12 nuts had to be held from the underside while being attached or detached by a vice grip, pliers, or socket wrench, which in turn forced us to tilt the robot up on end and stop work on any mods or fixes for the five or six minutes it took to change bumpers.

Simply put, there has to be a better way.
How do you and your team usually attach bumpers, and does anyone have ideas for quick and secure bumper changes?

I know that a lot of teams just use Velcro to change colors, but in an intense physical game like stronghold we were concerned about its integrity.
