Touratech crash guards
 

Touratechs are spendy units, and feel very fragile. I'm considering building some kind of crashguard/basket to protect the pannier in the event of a crash. Has anyone ever tryed this? Is it unnecesary? I hear a lot about crashing, but a suprisingly, very little about wrecked or severed panniers. Anything you guys can tell me would be greatly appreciated.
