I realized the 1x3x1mm ball bearings are really the perfect size being so small which is ideal to keep things compact but the only disadvantage is they only support I think 10lb weight put on them before they'd break. So I was going to use them for the first couple pulleys in the archimedes pulley system then switch to a plain bearing I made for when the forces get too high for the 1x3x1mm ball bearing to handle in the last couple pulleys. But recently it hit me that I can stack two of the 1x3x1mm bearings on top of eachother and use two fishing lines for that section of pulley to go around these double stacked pulleys in order to double the load capacity. If that is not enough I can add another single or double pulley below it and they would all come up together acting as a single pulley as far as the downgearing goes distributed across more than one bearing. With this approach I can use this type of ball bearing exclusively for everything since I can just add more and more of them for higher load situations in theory. I mean maybe for leg motor downgearing I could bump up to a beefier pulley but we'll see. So that is yet another nice breakthrough idea I had recently.

I'm currently wrapping up my 2nd archimedes pulley system prototype and will be posting an update on that soon.
