It's not the weight of the turtle that does the damage, it's the bite force. What's your landing net woven from....aircraft cable?

I used to catch large softshells and the only way to get them in the boat or up on the pier was with a landing net.
I was using the blue nylon knotted ones (that's what the net bag was made from). I did have one where it wouldn't fit into the net and the hook caught on the netting as it bounced off of the frame of the net. Hook stayed with the net, turtle disappeared into the lake. That was a BIG softshell!!
Yeah, the single strand ones are prone to kinking, and if that happens, it'll break pretty quickly. But, you don't need to crimp them like you need to crimp sleeves on the multi-strand.
We used both for saltwater fishing - wahoo and sharks. The single strand worked better because it was thinner and harder for the fish to see.
