>>11419424>>11419569Okay my apologies, work ran long and I'm also prepping for a trip in two days so this wasn't as elaborate as I wanted. I can still give some good parts you might want to look into, with a number of (but not all possible examples) pulled from my bins. Big thing to keep in mind with a lot of CCBS parts is much of them are cup focused rather than ball focused like G1 parts.
I'll run them down from left to right descending.
>G2 head, uses unique eyestalks>Technic pin connectors with ball joints, two variants>CCBS 1x3 beam, has a ball joint in the center hole that can be clipped onto>Mixel joints, smaller system in Lego bricks that fulfill the same function>Friction extenders I mentioned, with example of how they can link even to each other>Double-ended and skeleton CCBS joints>New Technic pin and pin/axle parts that are vital (there are others). The lone gray 1x2 brick with prongs is designs so you can fit Technic parts, usually the through-hole ballsThe rest of the parts are a variety of sizes of CCBS limbs and shells, including feet and hands at the bottom. There are plenty more types of these, but this is to give you an idea of the variety and how they have different connection points.
