Yeah I think Newbee are just better if you want POM gears.
I have the Matrix 3’s with the extended axles on one of my Lacroix boards and I like those also. But my Lacroix with the Matrix 3’s has belt drive, so I’m not feeling an apples vs: apples comparison. I want to try the dualities. Someday some dualities will show-up for a good price used and I’ll grab a set.
