I have one of MEC's guide silnylon guide tarps that I think is about 1.1 to 1.6 oz. I have had it for about 7 years now and have had no durability issues with it, with year round use. However, I don't drag it through the dirt or use it as a ground sheet.
Last year I sewed a 1.1 oz short wall pyramid hot tent. At first I thought I should have gotten a thicker fabric, but it seems pretty durable, just like the tarp.
Both are crazy light and pack small.
IMO 1.1 oz silnylon is pretty strong for most tarp/tents. The only thing I get worried about is catching it on a sharp branch ...but silpoly, silnylon, 1.1oz, 1.6oz, 1.9oz all have a good chance of ripping in that situation.

*is ripstop nylon the same as silnylon? I genuinely don't know.
slinylon= silicone treated nylon
ripstop nylon = nylon with extra fibers in a cross pattern for durability
They are often together as ripstop silnylon.
