I'm building a new cross bike. My prior one, to be my B bike, is configured as a 1x9. I ran a 42T Shimano ring in the inner position with a outer guard and an ngear inner guide. I'm going to build with a single front ring again. Should I get another Shimano ring, that's meant to go in the inner position, or get something else.

I stumbled across this on cyclocross world:

It's described as not having any offset. Will this give me some better chain line or should I stick to what I already tried?
