I ended up going with the straps too. Worked out really well. There is a little movement rotating around were it is connected to the straps. But very little and nothing I worry about at all.
If you get it to work I'm curious how you did it. I been looking at both that lock and the AXA Block XXL for my Allant 7+. And for the AXA Block XXL I can't find measurements to tell me if it will work or not.
