I actually have found mine to be surprisingly weak too. I didn't get major damage like you, but strands keep ripping along the edge and there is a small chunk missing, exposing the fibers. That was after like 3 days of use on blues, never hit any rocks or anything. I'm not sure if it's something that should be repaired. Mine is a TRS, without the bio-plastic topsheet.
