Favourite lightweight yet durable suitcase / luggage

[brockenspectre]

Hi all - Just wondering what is the current favourite lightweight/durable suitcase for checked baggage?

I bought my trusty hard-shell Samsonite case probably a decade ago now and while it is still serviceable - despite looking much-travelled - it weighs quite a bit even before I start packing and when I have finished its upwards of 25kg!! I am sure the market these days, must have new/lighter materials providing similar protection so ... what case would you recommend?

Thanks
