I have been considering ending my dark age for a while. This week I got myself a 42009 Mobile Crane as an introduction to (and starting a collection of) modern Technic. One thing I noticed was the orientation of the bushings, which is different from what I remember from my old sets (late eighties/early nineties). Whenever there was a choice, the round end of the bushing would go against the side with rotation. The end with the four teeth would go against the side where rotation was impossible/unwanted. That made me assume the round end has less friction. The 42009 instructions doesn't seem to care at all about this. The substeps sometimes inconsistent, showing a different orientation from the main steps. Did the old Technic teach me something that didn't matter? Have the Lego designers just gone lazy? Isn't the bushing asymmetric for a reason?
