I don't own one but from reviewing their website I noticed a couple of things. Hydrostatic resistance is 5,000mm which is better than SO @ 3,000mm. It doesn't look like the corners are as reinforced as the SO tarps. My guess is it will work as expected for 90% and the other 10% are Kifaru or bust.
If they made a smaller flat cut tarp I might be in the market but 15oz is to heavy for a tarp in my kit. It looks like I will be running the Gunnison.
