I've read the cloak is surprisingly quite restrictive. It's made of multiple parts yet still hinders the legs. I've also read that Tamashii gave this Trunks not only a new neck peg that's medium sized and doesn't work with any previous heads but the faces were also modified and can't fit on the SS armor Trunks heads. If there was any doubt that Tamashii doesn't want people swapping parts around, there shouldn't be after this release (which is absurd, part swapping is one of the most appealing aspects of the line).
At least it's not Whis level of restriction. And the whole swapping thing definitely was a downer for me
