Anyone have any suggestions for a lightweight silpoly tarp that would provide adequate coverage for the WB Ridgerunner in mild/moderate weather? Something <14 oz would be nice and ideally would like to find something around 12 oz. Was wondering if a 12' Quest Tarp from Hammock Gear or a 12' Dutchware Xenon might work. I've currently got a 13' Mountainfly but would like to have a lightweight option for trips where I don't need as much coverage.
