Went with 2x layers of a 6k weave on top and thicker single 12k plain on the bottom... because they were surplus drops on the shelf. Haven't had a chance to test as the waters kinda hard here for a few more months. The rationale was double the tops to help with single point perforation from gravel in my shoe tread.
Hard to say if it would be right for you with your weight requirements. I'll probably add more stiffeners as I'm well north of 180, it seems OK for the wife but she's fair bit under 180.
