Hey, just saw this and thought of you.
I'm going to try it too.
Btw, I heard a Chris Duffin tutorial about Ab rollouts and he talked about not arching your back so much, but crunching up your abs and sort of relaxing your upper back so that you reduce strain on the lower back. Lower back strain is my bigest problem with rollouts, so I'm going to give this a try. He doesn't really explain how to do it, but I get the general theme he is going for. We'll see.
Let me know if any of this is helpful for you. I will tell you whatever I learn from my end.
I am Anton Zdravko Martin!
