Could you move 600 litres around in one go? I do know what you mean -- they are much better in terms of size. I just find them prone to damage. In the early days of council kerbside recycling collections, we were given bags made of the same material and they were getting damaged and broken when people put anything other than tin cans in!
The '1 tonne builders bags' are much tougher (they're used to transport ballast, sand, soil, etc.) and you can often pick them up for free on Marketplace. New ones are only a few quid.
