Better exclusive then a mini holo IM or mini arc reactor I think.
Cool video. Budget stark do you think the changed shoulder articulation is in part due to the lack of swappable shoulder armor? When it's designed to be taken apart it needs extra sturdiness that no longer is required when the shoulder armor is static. I have not gotten my 43 yet so I have not had the chance to take a good look at it.
After seeing them side by side like that, I prefer the look of the 42 more. The colour distribution just gels with the panel lines better, where I think on the 43 the placement of red and gold make it look a bit fussy.
