Despite all the crap that Hero Factory Bootlegs get, there honestly are actually a few good custom pieces for MOCing that you can get from these. Some of which bridge the gap between the Technic and CCBS systems.
For example(and this one is my favorite), "Bot Factory" and "Earth Heroes" have a 1.0/2 0 hybrid chest piece, being a 2.0 chestplate with a 1.0 core.
I love this because I like the 2.0 chestplate, but not its core, and I like the 1.0 core but not the chestplate. Now, I can have the best of both worlds!
Additionally, another example from these brands is a 2.0 helmet that can fit on a Glatorian head.
Anyways, what are your thoughts on this matter?
