I came across this After Effect rig example

and I wanted to try the slider approach in Moho, I got most of the way there except I cant lock a pin bone to move on 1 axis only, be it x or y. Does anyone know if a way to do it?

Parent the bone to a veeerrrryyyy long bone and set that bone's angle constraint to only cover the slider range. If it's pivot is far enough, it will look like a straight line.

the pin bones are targets for the shy bones that have smart actions on them, but i cant keep them on the line indicator

Here's how it would work in your file: http://www.filedropper.com/eyetestrigedit

The only drawback is that the long bones do get keyframed using manipulate bones on the sliders.
