OK, I'll give them the option next time for the 6mm - good idea!
I'd only reckon it would work here for longer term, not necessarily more resilient. The fact that the panel weighs 2x as much may help to keep it from swinging back and forth so frequently, but if god wants that panel, he'll take it and eat it for lunch.I don't think 6mm really provides a lot more strength from tearing.
