I have one of the terrarossa tarps, and from memory it's one of the polyester tarps (doesn't get slack in the wet, but not as stretchy)
For the weight/size, it's very good. At the end of the day you pick two from cheap, durable, and light, and it seems to be durable and light. For reference with rigging and stakes, it's 720g and I'd call it a six-person tarp for most things. I don't have the dimensions to hand but it's on the larger size, easily big enough for two people to sleep under with gear.
In my way of doing things, a group shelter's weight should offset another bit of kit, say a larger FAK or cookware. So in the end yeah half a kilo might be a bit much, but anything under that, so long as it's balanced off by someone else's load is well within what I would expect. Mine is large, but it's also either a solo shelter, or someone else is carrying gear to make up for it as a backup.
